I love the background and the walls, but the pulpit seems a little bit too geometrical. The lighting doesn't match.
Congrats anyway =)
Looks great. Biggest complaint would have to be the fact that the tiles (that is, the floor) looks a little pillowed around the edges. It could also use a little bit more lightsource work, I think; but aside from that, it looks great. I love the background with the mountains and the moon.
Fantastic picture! I've always liked gameboy style pixel art. You've used dithering technique really well in the mountains.
Congratulations!
tinted green like the original!
