I like this... but there are some small details...
First is that you made the box translucent, so we see the door behind it.
Second being the posters at nat's house have ponies on them that are bigger than the poster itself.
Third, When nat just wakes up, the doorknob is on the right side of the door, but when nat opens it it's on the left instead, yet the door is open and we're still looking at the image in the same way as before.
Other than those things and the art, it's relatively okay.
I'd say I don't want to be in this, though since you're already portraying me in it I guess I don't have much of a choice other than say go ahead, might be interesting.
EDIT: In truth though it's not that bad and I say you should continue this... but also take notes on RPG's spam story.
