I was loving it until I saw the scan lines in the corner...that's when I started yelling into a wall.
Like Nantosh pointed out colours and text work well and everything in that feet/leg area is ace. It's just that your lighting is really intense, either lower that down or go back and pop some of the shading to bring a bit of contrast back into the piece. Also what are you hiding under that clipping mask....if there is a version without it I would like to see because it kinda detracts from the focal. Other that good job.
