Left Hand

My left handThis is a pencil sketch of my left hand. It's possibly a little overworked. Part of this came from an error in the back on the hand which I tried to correct by erasing. This left a white blotch (obviously) so I tried to cover it with hatching. It didn't work so I tried to darken the rest to match! Overall, I'm pretty happy with the shape, less happy with the tone.
