Awesome

I like this one

Pretty cool!

I like your drawing but the neck is a bit too small and curves in a bit too much. I would reccomend making it almost out to where the cheekbones are but a little inward if you are drawing a guy, for girls it's about to the edge of the eyes. If you still have trouble, message me and I'll draw you what I'm trying to explain. Despite that, I really liked how your drawing looks sketched and realistic at the same time (primarily because of the lighting effects. You have a very interesting drawing style!
