dang...what happened...just look at the change...from cartoon to mangs style...its crazy O_O;

It's good if you like it! Something changed, that's obvious.

Really? Maybe on another website. Here...probably not,unless I feel its worth the time and effort to make one. <v<''

Make the pupils a bit larger, show a bit more relaxed-ness with the hair (Give it a reason why his bangs stand up like that. show stuff like threads of hair, some splits. define it a little. give it highlights (Not like girl highlights, lol) show some lights angles and dark angles. the lineart its decent, but try rounding out the edges, like his chin, try not to make it too sharp (If you want to make it look more like a boy, box the chin a little.) same with the side of the face/cheek bone. I would say experiment with a little rounding if not a mix of both.

now, this is just my constructive criticism ^^ not trying to change how you draw, this is good, dont get me wrong, jut giving you some ideas that might help you :v

:< I NEEC IMPROVEMENT

STUDY THE ORIGINAL JP F--- MANGA

Ok, ok. I don't like theneyes because it's not my style. It looks too Diamondshaped and the coloring of the eyes are much more/better than the rest of his body and that makes his eyes stand out too much. Actually you could say that there is nothing wrong with the eyes, but more with Mark himself.
I just noticed that you're learning to draw Mark from Mark XD

Funny how Retro says that noone has hair simply with spikes coming out of it, but look at Naruto XD But you should improve the hair. You don't want him to look like Naruto, do you?

Fine, show me the improved eye, but I hope you understand that drawing the eyes is the best thing you can do and it seems that you only want to improve that right now.
