I can see one thing off the bat that doesn't seem right. The arms are too short. If you put yourself in that position, your own arm would be bent, and not straight.

I sadly enough don't have the time to do a full critique, and I have to say, that you do handle the pencil quite well in general. I might come back to this later on ^^

i don't know enough about anatomy to point out the faults. i don't see fault with the arms myself, as in them looking to short and needing to be bent. i'm assumnig he's in the process of standing else i may have had the shoulders raised more. i would have thought the legs were a bit short if anything. but as i said, i don't really know enough. all i can really say is the head looks great; cute face and nice texture on the horns.

Yes, the legs are driving me crazy trying to get right :O

you'll get there in the end. it's looking really nice. maybe erase from the hip, take a break for a while and try again. just wish i could help more but i am a total novice.

I agree with a commenter above, HIS left leg is a bit too short and maybe the torso needs to be lengthened a tad more? Otherwise this is coming out very freaking well, great efforts on getting the roughed out areas in there (positioning the body with lines and such). I love seeing great graphite works in the making so keep on with the shading! :D
