The wood is beautiful. To me, the wood has an oriental-Japanese-inspired vibe. This wall's paint is nice, if your can match. Here's a method of choosing wall paint: http://www.lindaholtinteriors.com/2011/07/testing-wall-color-101/ Can you keep just the curtain panels and remove the sheers? At a later time, a non-patterned curtain panel the color of wall. I saw the art and I think it is OK, but not for this room. Perhaps in a bedroom? I don't understand the theme you have going? Giraffes? Clocks? If you like clocks, remove the giraffes and buy something like a large round wrought iron "clock". Note also the rug, pillows & throw as inspiration for your room. Perhaps the TV console in a lighter tone wood like their end tables (your room = too much black).

You could also bring in some texture with bamboo sticks or decorative branches and help balance a bit the height of your room with small scale furniture. Spray paint them if you find the perfect size and shape but they aren't the color that you need. Ikea carries white decorative stalks for a very good price. the ones in the 1st picture hold well with small kids around and you don't need a vase for them. there are washi paper or crinkly paper floor lamps with a soft beautifully diffused glow For a budget friendly version check ikea or target http://www.ikea.com/us/en/catalog/products/80028552/

If you can't clean up the painted edge, you could always add a 1x3 piece of wood as molding. You can even carry it up to the ceiling to frame that wallpaper. I don't see that paint color in the wallpaper, or maybe it's a lighter version of the flower centers. Maybe stencil on a design using the darker color, or another color from the wallpaper to help tie it together. Then narrow floating shelves or vertical frames or something in the painted areas it you feel you need it. Maybe turn the bed around so the wallpaper is the headboard.

This Cabinet is $155 at Ikea. You could take the 4 items you had hung, and put them in a "shadow box", or individual deep frames to tie then together, to create I piece that looks more substantial on the wall, Then add a little ledge for photos, and you would even have room on the cabinet for the cool bottles that were on the floor, and that cool chest could definitely find a home as an end table, or entry table. You could also add a larger plant in a really nice pot in turquoise. The cut and paste renditions arent always completely accurate in scale.
