whoa, did you say half an hour to render one frame? you must be a patient man. no wonder your phone is looking so real.
i love your texturing of the mouse and mousette (or should i be calling her daisey?)
one thing, though. where the table meets the wall. it seems to end too suddenly. the edge seems too sharp to me. maybe, you could add a bit of bevel, to soften it a bit? or maybe add shadow falling on the wall...
