I think this one turned out much MUCH better than the last attempt, partially since I had a better reference (full body shot as opposed to the inaccurate toy), and partially since I've been drawing for at least an hour a day for a few months so I have been improving. The pose makes it look like he's jumping out of a closet so I added the jet exhaust and background to make it look like he's chasing jets or other bots mid-air and about to pounce.

Pencil only this time. Enjoy.

EDIT: Thickened some lines and added some extra details.
