You got the energy and the gesture, which is a good start! You have a clean line and a good understanding of anatomy.
I would recommend using more structure and guidelines - it will help you to understand the anatomy and maybe even draw faster!
All in all, I think you have a good hand and a good start. Don't be afraid to use guidelines to help you be a better sketcher! good luck!
Thanks! I will try that.
i do not know but somehow your drawings remindes me on picasso skatching(not in cubisam or apstract phase). i do not have any thing to say exept that is perfect, but continue practice there is no end in art making;).
