I hope you dont find my critique rude but I liked your drawing and this is just tips that you may or may not like.I am not the best drawer or draw anything amazing but i still tryto improve.1)The chins is too pointy and doesnt align well with the face.2)The nose has to much detail, while the rest of the face doesnt.3)the line for the elbow needed to be move according to the bone structure4)All the hands seem to be unproportional ...try adding more shadows to show off the structure of the hands.(I suck at hands)5) Thats just a really high cheek bone IMO.Overall I loved it and wouldnt have critiqued and given my advice if I didnt like it.I hope you didnt find what I said offense.Keep on drawing :]
