He's a snake type isn't he?
If so, I'd try to give him OR a mask (like kakashi from Naruto) or a mouth with fangs or so.
Now I'm kinda missing something around that area.
I've got to say, I love the fact that you're improving so doddamn fast!
I mean dang!
More detailed, more in proportion, more fiercy!
I've seen some coloured works, and they look very promising as well!
I'm guessing you learned a lot of Molly too! (awesome gallery she has, too bad she's making a other account ) I'll look if I can find her again
(seen her work, and her style is similiar to yours )

I do think you should colour some of your works more.
Colour makes your work much more attractive for more people (people fav most of my most colourfull works ) Aaaaand ir shows more efford and detail.
You produce a lot of sketches at the moment (wich is good!) and I saw you were making a portofolio?(am I right?)
I'd try to add some colourfull works as well!(cuz they're worth showing, it's one of your strtong points)

AGAIN a long comment xD
Haha gunna go to bed now.
Bye!

hah thanks for the nice comment. and yes i'd defintely add some nice colorful pictures in my portfolio too .
