Thats much better, though the lack of and shading on the other side of the hand is a little strange. Might I suggest adding a few light spots there?
Also, I'm not sure if this part is still wip or what, but I'd suggest reshading the can - add a bit more contrast too it, specifically. Also maybe tint the dark greys with a hint of blue or another shade, perhaps some hints of skin tone (to give it somewhat of a more reflective look). Either way I'd suggest not using neutral gray, particularly in combination with actual colors.
