Although the lack of texture, shading and flaws in the perspective, this is a cute little scene.
I always liked medieval themed art works, so I think this has a huge potential if you fix its flaws.
Looks nice espcially the chararcter, but the perspective is fairly wrong.
Each of those lines should all converge to one point on the horizon, because they are all, hypothetically, parallel lines.
Edit: ugh, so many perspective ninja's!

I agree with Parker on the crits regarding perspective. The colors seem a bit dull as well, but that may just be me nitpicking. Either way, a solid start to the room.
Seems there are a few questionable placements just from a practical perspective.
Windows on all sides, one directly beside the furnace so it could not easily be used. And it makes it necessary that this is a solitary room or some windows would be looking into the adjoining room.
The shelves seem a bit close to the table so items could not be reached from most of it.
The perspective is off for many objects.
Sorry, for all the criticisms, but I love room scenes and I like to talk about them and try to help.
About the perspective, I kinda feel it's a reference to Mother's games style (www.super-famicom.jp/pic/rev/mother2_00.jpg). :D
