I'm an artist too and i wish i could colored like you, its really amazing BUT your drawing skills need some more fine-tuning, i hope your not getting pissed or think that I'm just some hater or envious coze I'm not that immature.

So let me put critic on your picture to help you improve on your skills.
Your character has a too small torso, too long legs, too big foots (Yes i know he has armor on they are still to big) and his left arm do look kinda awkward like its dislocated from its Torso. Hope that helps
