Good morning, SentientKarp, and welcome aboard. Thanks for posting your Imgur link. I really must say that your drawings are filled to the brim with direction, weight, solidity, and personality in most every image you've posted, so please do push yourself more harder.
So, if I was to suggest some feedback to improve or refine your poses and expressions, then I think or feel that these drawings all look or seem too timider to me. Would you like to please loosen up your lines shapes with our interactive drawing tutorial, even if it's all figure studies, here?
The reason why is because, your lines of action and exaggeration will be rapidly articulated lesser than stiffer, but more livelier, expressive but gutsier. If you really loosen up your poses and expressions that way, then your storytelling attitudes and emotions will be even more than entertaining. Also, kindly look into the Vilppu Drawing Manual PDF and The Little Book of Talent on Kindle, by Daniel Coyle.
Good luck from me to your works in progress.
