You are a great artist . Your way of drawing face and body is remarkable. I think you could even work safe for work at some studio as a manga artist .cbut I won't support you because of one reason. You draw the d to big . 20% smaller and it would be more realistic.i am European with an slightly bigger than average dick and mine would be small compared to it m you could consider to make to draw smaller sometimes or make an variant set wit 2 different sizes or something.just an idea .whatever you do I wish you the best .
