Pretty good!
For early animations this is really good! Things to improve on - background graphics are needed. It's boring with nothing. Make something with a point, or a twist, or a moral, or something, and it'll do better. I liked your animation style, I hope you'll continue because that was quite good! Niggly things, I'd keep his mouth in his face. And parts were a bit lazy, like not showing the blasting up with the smoke - I know it would've taken a while but it would've been cool. The way the jetpack folded out was great! All the best.
