Aaron Hopwood:

With some cleaned up line-work this could look really nice.

Wayne Skylar:

Where are his eyes?

John McSwiggin:

Was this rotoscoped? The animation is so smooth.

Brian W.:

Nice work. Your only strong pose appears to be at the end. Make more use of strong poses and key frames throughout the work. Movement is linear, again until the end when he raises the gun. And even then, deviation from linear is minimal. Don't let your commitment to smoothness prevent you from attaining movement that is more natural or even ballistic.
