Hmmm... Its a bit better than those Vegeta and Trunks-being-shot pic... but you still need
alot of practice. :-/ Keep drawing and practising... :yes:
Some critisism... well, alot of critis:
Okay... His arms: The elbow bends on the arms should be at the waist. (stand up, stiff, arms down completely next to body, and compare, then youll see what i mean)
His legs: Pants are okay :-/They look kinda like snowpants, though. Just too many clothe wrinkles. the wrinkles should come from the back of the knees the rest should be somewhat straighter.
The abs are very messed up beyond belief. The eyes, eyebrows and nose needs work. his shirt looks very unrealistic (well, all the pic looks unrealistic :-/) but it cuts in half and has perfect rip spikes. His muscles are strongly deformed. I dont remember his having a necklace.
His hair, thats half-decent
Good luck on your next picture. A recource to check out for drawing and drawing manga:
