lacrimode:

i am trying hard to learn how to draw backgrounds but then i get all poopy

I checked all the vanishing points, and they all line up pretty good, except for the corner of the desk, and the bed itself could be just a little bit more defined as far as it’s edges go.  There’s also a slight 3 point perspective going on, which I thought looked a little odd for a close interior scene.  Not that it can’t happen, but the room looks less warped when the lines are straight. 

I also marked in green were there are some missing edges that would normally be seen.

The horizon is also at a tall person’s perspective compared to the figure you’ve laid in.  (I think though, the figure is at a correct average height compared to the desk.)  Figuring out where your observer is helps me a lot when I’m doing perspective.
