I found it quite amusing how 3 members rated this -1 on the public queue, probably because they didn't bother to view the detail image.
I'm guessing this would look really nice ingame. Reminds me strongly of Metal Slug. I think you could have done with a better 'flash' for the explosion, because when out of context it looks quite off putting. Would have also liked to see the smoke dispurse with a little more freedom.
Very nicely done though!
