Man, I can't even count how many times I've drawn Ariel. She's a beauty! I really like your black and white paintings, you seem to do really well with value. I'd just be careful with the dragon's head, it seems a little disconnected from the neck. Keep it up!
Looks good! The eyes seem like they're on a flat surface, though, rather than a curved head.
Yeah, that portrait has several issues with the eyes and the mouth. Just zoom out a lot and you'll see it's completely deformed. I even think it's better to just redo the whole thing than to fix the problems. What do you think?
I think you're doing quite well. What I think you really have going for you is determination. You're keeping up with actually posting your stuff and making sure you do the drawings. It's a lot better than most (me included most of th etime) are doing.
And you're getting better the more you practiced. I've been doing the peer project stuff here to work on my shadows and values and it's been helping me a lot. Granted I've been really lazy about posting in my sketchbook BUT the stuff really is helping lol. You should check it out.
