The intense look makes it seem like she just pulled off an amazing dance routine, and is now staring intently at the security camera as to challenge the security guard. :P

Great piece!
Very ambitious camera angle and you always seem to have a knack for reflective surfaces.
Only thing I could maybe point out is that it seems like the bushes on the left are more detailed than the bushes on the right, despite the ones on the right being closer to the camera, which might mean that they'd be just as if not more detailed in the leaves factor.
But hey, from the description alone you were putting off sleep, so maybe it's a good thing you put the stylus down when the piece is practically perfect. lol
Nice work!
