hey nice to see your works again . well after seing some of your stuffs i feel that you have a certain affinity to draw faces more than anything else .
well you should try doing the whole body too. and try more dynamic pose instead of just a standing pose or a very static pose if u know what i mean.
you have improved you line quality alot but may be its just me but you are concentrating on the lines more than the form. and bcoz of that i thihnk some sketches have odd proportions. lol i dont know how to point out the particular sketch i am too dumb at that XD
oh and also the hands need more work .
lol sorry if i sound rude or anything . and the funny part is i need to do the same thing as i pointed out to you lol.
keep them coming btw
