You no longer need to 2x your images, since Firefox 3.6 has arrived(and fixed the blurring issue)! I really like these. They're very simple, yet seem to imply much more detail than there actually is. In fact, for some reason it reminds me of Cave Story. For the computer desk, what you can do to fix the issue of the two sides not matching:

Instead of just making the cabinet side longer, and thus making it hit the other side and destroying the gap, you can just balance them out.

Also, the bed seems a little high(it's as high as the desk, which is odd )

Dusty - I've got Firefox 3.6, and it still blurs it out when I zoom in (although that just might be a Windows 7 thing, since it happens in IE8 and Chrome 4, too). NVM, a simple edit to a CSS file in my AppData folder did the trick.
SirBilly - I like it, but that indent on the bookshelf is bugging me.  The grays don't really go well with the brown.  I'll try to make an edit without destroying your palette, and I'll post it once I finish.
Here's an edit -  The black may be a bit too harsh, but I didn't want to edit your palette.
