All right first thing I think you need to balance your spacing some shots are just way too close or feel too cramped within the paneling, try make more defined shapes that have a clear purpose like when the body is being crumbled up it's hard to tell exactly what's happening, and also have a lot of reference it allows you to base characters environment and other objects that help carry the story on real life but if you don't feel comfortable with having a reference beside, you must always make sure to be observing and bring real life inspiration to your work, like certain shapes on a tree or car or even action figures, I recommend looking up the artist Kim Jung gi on Proko, for me that's what motivates me and remind me of what I need to do to get better, observe digest and imitate, do often and have fun.
