depending on measurements,

a tall unit on each side of the window with a desk/countertop under the window.

A good edit is in order. You only need what you use/need.

Very hard to advise without measurements. Draw the room on graph paper accurately. Cut out shapes for your furniture. It looks like you have some large stuffed animals in there. I'd find a dead corner somewhere in your house for them.

The room is 11x10. Stuffies are usually on bed or piled in the corner of her dresser and wall. I know it seems like a lot but there are only about eight that don’t fit in her wicker baskets.

Three days, NO drawing with any and all dimensions, ( walls, window doors, entry door all of it ) will NOT get you help. Sorry......it's guesswork. Which is why you are now stuck in a mess: )

Decluttering/downsizing before decorating is a major rule for adults and children when creating happy, relaxing spaces that feel airy and light. You need to subtract a ton of stuff before you bring in yet more furniture into this jam packed space.

Here's how to rethink the whole setup. Except for bed, dresser, and vanity table, remove everything taking up floor space--wicker baskets, bins, random shelves, all the stuff. (What's a TV doing in a kid's bed room anyway? That's what a family rooms or living rooms are for.)

Once you clear the room, move the dresser to wall where that too-high-up art work is. (Center of art work should always be at eye level like in a gallery, but I digress.) Then move the bed to the center of the wall it's on. (If there's any budget, after you seriously reorganize, get a storage bed or one with a pullout for friend sleepovers. Your future teenager will thank you.) Until then get rolling drawers with covers for under the current bed for excess stuffies beyond a few that go on the bed.

Get nice matching bedding, nice roll-up window shade, a colorful bulletin board and/or white board for friend messages, and one or two art works your daughter can create herself or photos of her friends, family, favorite places, etc. blown up and framed. Get her in on the organization first then cute wall decor.

With the bed in the middle of the room, do what @lisedv brilliantly suggests--two Pax cabinets flanking the windows with a shelf desk in between. Do not, do not bring back any more baskets, little shelves, etc. etc. The room will only have the centered bed, the Pax cabinets by the window with desk in between, dresser, and fun vanity. Your 8-year old does not need anything else.

Once you have the window flanking cabinets, set up do a parent/daughter organizing morning for the downsized clothes and possessions. Use dresser for underwear, nightwear, socks, tee shirts. Use Pax cabinets for other possessions and closet for pants and sweatshirts, dress up clothes, sports clothes. Put a poster on the closet door, not droopy shoe bag and random clothes. Have an atrractive, organized and functional system.

You asked for serious help. That's mine along with help from some great design people on Houzz.

Some inspiration photos showing room with window desk and cabinets/bookshelves flanking window. Notice Roman blackout shades in two of the photos--neater than droopy curtains.

Thanks all! I realize these photos make her room look like a mess. It is a mess. It’s not always like this. The artwork up high is not usually there lol. I’ll post an after pic when we are done! Thanks for the advice.

You don't have a "plan"

You haven't taken the time to do as asked.....which would be a drawing and a MEASURE of the walls, window, openings et, uploaded as a jepg in the comments.

That would get you very concrete suggestions. A better space.

I guess they got all the help they needed .
