This one is very nice! nice name also :p

I really like the colors on it
Great work.

Updated!
I tried to improve the gun, particularly.

Thanks for all your comments, everyone.

Aww...It's so tiny. Makes me want to hug it. Nice colors.

Smooth, but not realistic at all.

But I guess you're going for cartoony anyway.

That is a cool character and nice work on the animation.

 

It looks great, and very comical with the little stubby legs.
I dont like how the gun moves! Maybe you can try making the lighting on it shift a bit as it moves up and down. It just seems so immobile while the rest of the sprite jiggles and moves.
And also, maybe shorten it on the frames where its pointing up, else it looks like Montgomery stretches it like taffy instead of just running with it.
Or maybe the problem is just that the guns' end doesnt rotate at all as it moves up. Maybe its that. Not sure. mmmh. mmmmmmmh. mh.

But great piece!

Awesome! I like it very much
