No word art..... I think the 2 pieces are too wide together. The art should be about 2/3 the width of the dresser

Hi Maddie. You're off to a great start. But I do see areas that can be tweaked and improved on. I agree that there is a struggle with the desk placement and dresser placement. Is this a shared college apt where you need a desk in your room? I see a chair peaking out from the corner. What does that side of the room look like? Stand at the window to the right of your bed and take a photo that captures all of the opposite side of the room and then do the same from the left side of your bed so we can get an idea of actual space. Can you measure and draw a floorpan? You have a lot in the room and there may be alternator arrangements that work better. As far s above your bed two or three square art pieces depending on their size would work well. You lamps are a bit on the short side. I see the mustard throw and pillows. Is this a color you want incorporated in the room? I would lose the mirror above the dresser. It dates the space. I am not opposed to a mirror but an interesting one that hangs on the wall would be a more updated feature. Round and framed in the same color as your hardware like a thin black metal framed round mirror for instance. Is you desk also used as a vanity? Is that the reason for the mirror there?

It depends on your style/what you like. For instance, in my living room I have watercolours, oils, charcoal drawings on rice paper (and other mediums), none matching the decor/color choices. If you want to complement the duvet, muted shades might be easier to choose. Think about what you are drawn to: landscapes, botanicals, abstracts, vintage, etc. Size, frame, one vs sets, or a collage are also considerations.
