Extremely short, but first efforts are often that way. It's very rough, but passable. Even with the crudeness of the sketches, you've included some nice details, like the suit's knee spikes, so it's obvious that you know the source material. It'd be nice to see you spend some more time on this exact thing and see how much you can improve it - cleaning up the line quality and adding more in-between frames and such. Good job, and keep practicing!
