Very Nice! One comment though. On your opening curtains it seems somewhat unnatural in the last frame to be SO straight. You might want those lines to mimic those on the second frame (slightly diagonal) to make it look better. Also, the third frame should not be SO angular... again, it looks a little unnatural.
This is only from visual, I'm not sure how it looks in game. Just the exactly straight last frame and the extremely angular third frame seem a bit unnatural.
