Yeah, my biggest suggestion would be larger art over both couches -- 50-75% the length of the couch. If you look for something with the same aqua as your area rug (which really should be larger, but let's leave that for now), it will make the room feel more intentionally planned.

Buy a beige, brown or blue cover for the futon couch. Add some more fiberfill padding to the other sofa's back cushions. As acm suggests, some large artwork you can take with you would be good.

There is something very cozy about your room..feels like home. And it should, rental or not.

My advice, coming from somebody who rented a lot, moved a lot, etc-buy art that you love..that, you'll be always able to take with you and find a place for it. Think of it like people think of books and travels..something that stays with you regardless where you are.

Don't look for themed..:) Never ever. Look for whatever you love whether you can explain it to yourself right away or not. If it will have a theme the theme will emerge spontaneously, don't worry..we are the ones who unify our art..:) We're drawn to it for some reason. That reason, whether very on the surface or deeply hidden, will tie your art together, without you making any additional efforts (except for falling in love with it of course)

Check local art and craft festivals, street fairs, and all the usual on-line suspects-eBay, Etsy, etc for original works or prints bought from artists (if say the original is too expensive or is sold out, but you love it and can't stop thinking about it)

You can add lights (which can be bought very cheap if you go the vintage route, and can be very interesting too) and still be able to incorporate them in your future place. Chandeliers are tricky, but table lamps, floor lamps, and plug in sconces are easy to find and to incorporate later into many schemes. As long as you know what style speaks to you. Or what styles speak to you-can be plural. Lights are easy to mix and match.

You can add fabrics. Throws, pillows..change the rug that bothers you for one that makes your living easier. Again, if you're not against owning second hand-check eBay, Chairish, Etsy, Everything But The House. If you'd rather buy new-look into ecarpetgallery (great prices, and terms, even on hand knotted wool ones), or check inside-ouside rugs, these are great for withstanding the spills and are cheaper and look better and better as demand for them probably grows.

Fabrics-you can make them work too later. If not in the future living then say in one of the bedrooms.

You can add plants of course.

You can add a bigger tray for your ottoman. Few things are as useful as trays, in my opinion.

You can add a small end table that youl'll be able to take with you anywhere

The only rule: shouldn't be a placeholder. Something you really like. And it might cost 20 bucks on yard sale, that's not the point. The point is-something you can envision liking for longer.

Unfortunately I can't see the whole room..is it a desk, or the dining table, that is seen on the last photo?

Would you like specific suggestions on something like a rug?

Don't let the fact that you rent stop you too much from making it comfortable for you. Some people never have their own place. These who fall into this "everything is temporary anyway" mode are usually unhappier. I made this mistake once. It didn't help anything. Houses should uplift us and cocoon us, whether we pay rent or mortgage(lol).

Big, beautiful art! Consider engineer or poster prints from staples/office max--you can get photos or images found online printed pretty cheap. Use a strip of wood at top and bottom to mount/frame for super cheap.

A new, larger rug that you're more happy with. I find good ones at rugsusa.com.

Colorful pillows or blankets. If you can sew, this is easy. If not, try walmart or ikea for i expensive options.

Some consistent color through all these elements will pull the room together more.

And the only theme you need for art is "I love it"!

just found a cool site(mentioned in other thread..never saw these guys before) don't know about the quality, but the OP there likes her sofa. And sofas are hard to get right.

check them out..

other cool inexpensive stores for new-IKEA of course..Urban Outfitters(that had recently 40% off furniture..don't know whether they do still) ..for fabrics-your local TJ Maxx and Tuesday Morning if you have one

check also flash sales sites like Gilt, Hautelook, Ruelala and OneKingsLane on deals on rugs, throw pillows, throws, trays, etc.

if you have flea markets in your area..wow, that can be a lovely Sunday..:)

vintage stores etcetera. Don't miss these.

Craigslist of course.

It's all matching too much beige.

Art hung at eye level. Yes get art on those walls. Maybe one large and two medium on other wall.

New standing lamp. Sell the old one or reuse.

Sell the coffee table. Use end tables or small stackable since your space is relatively tight.

I wholeheartedly agree with April!

To add to her wonderful suggestons... I would add a throw on your futon as well as get some nice throw pillows. Maybe some curtains or sheers for the windows? You can take those when you go.

I also agree that lamps, lamps and more lamps are your friends. They provide light and give off a warm glow. It is nice to have mid level light throughout your space. You would be surprised at what a difference it makes! For this you may need to find some end tables. For great deals check out CL.

Of course I agree with the art suggestions and a new rug.

Your room has some lovely character. You can't always say that about a rental!
