the only thing I genuinely do not like are the arms. They are bothering me greatly haha, one thing i can point out about them is for example the back arm. The lineweight of the biceps should not be in front of the deltoid. Likewise you can push the biceps a bit to flow more from deltoid to underarm, but for the love of all that is holy dont make hem two balls like right now. I can see in th eother parts of your drawing you certainly have the skills to draw those in a less cartoonesque manner instead of stylized.
