Amazing stuff here, Cos...though Claudia reminds me more of Angelina Jolie in that shot;)

Hey Cos!
Thanks for posting more of your stuff!!! You know I love your sketches (and not just cuz you keep using some of my all-time favorite ladies as your subject matter)! In fact, I basically just wanted to post to say this:

MORE PLEASE!

Keep drawing and keep posting!
Regarding previous comments -the thing I love about Cos' art is: I see Cos in the art. I'm not necessarily looking for photo-realism as the measure of quality in someone's art (though I think you do a ruttin' fantastic job in that regard, Cos). I get more of a kick out of, like I said, seeing Cos' impression, (or maybe expression is a better word) in these portraits.
Love it Cos! Ditto the others' encouragement! Keep it up! We'll keep ours eyes out for more...

Well, you asked wo here goes.
Your eyes are very nice but the iris/pupil areas needs to be a little larger on both pics and the eyes might need to be a bit closer together. Especially on Vala.
Your Jaw lines are also a bit angular (again, especially on Vala). You should try and soften that a bit.

That being said, these are great. Might you be posting anything in the BSR soon?

Wow... I wish I could draw like that. You do the eyes really well.

Cos, nice work again!!

Only thing I can say as far a critic goes, is that you draw one side of the face spot on, perfect even, but have trouble with the other side.

But your trouble stuff is better than my best effort, so good work!!
