Hey there! Great job! I love the character :) You are doing way too many "chicken scratches", which means, instead of making coherent fluid lines they are messier and timid. You should work on your line quality, it will do magic to your artworks. If your lines are cleaner, you will notice your mistakes way faster and it will make your drawings more understandable. Other than that, try to work on your gesture. I believe @Mike Mattesi has a few videos both on Proko and on his own channel where he explains gesture. You should definitely check him out :) Keep up the good work mate! :)

Hey Dennis, Looking pretty good. I took a look at some of your other drawings, and it looks like you're putting in some time to level up. Be patient, it takes time. I see that you've been working on a lot of anatomy study, but be sure to work on studying perspective as well. As you construct your figures, being able to draw boxes and cylinders in any position form your imagination with impunity will unlock a lot of potential in you. There is also a lot of hidden perspective in the figure, hidden parallels, that if you find them, it can ground your figure. In the case of this figure, be sure to understand where your horizon line is, so that you can aim any hidden parallels to them. If the figure is standing straight (not leaning on a hip for instance) the lines between the heels, the knees, the shoulders, and even the abs and bottom of the pecs, will create these hidden parallels that you can use. Not finding these will leave your figure looking a little disjointed. One other thing I would suggest is that if you're interested in getting better at comic book style drawings, start making comics--even if it's just short stories. It will force you to solve lots of problems, and in solving those problems, you'll level up faster. Good job! Keep at it. I look forward to seeing more art from you.
