Those look great! My critique would be that the male has a wider face/jaw, his hair is a bit shorter on the top and his eyes are slightly more narrow with his scar going vertically under the eye instead of horizontal. For the female she has a little thinner of a face with sharper features and curlier hair. Otherwise, I love them! My male character is a wide built guy while my female is much smaller so i appreciate you asking for changes/opinions.

Ok, made the changes~
The reason why the girl looks more defined is because I went over it w/ a pen, since the pencil Im using wasnt getting as dark as I wanted it to.
(Again with face alignment problems... I should check more when sketching >.>; but then again, cant flip canvas irl.)

They're perfect! I love it!

Here are two pose options~



(& will fix the anatomy when it gets to it. ^-^; )

Honestly, I like them both equally so whichever one you find more appealing to draw works for me!

not sure what happened, I think I messed up. Just a headshot though please.

Ok, awsome! I'll get back to it~ c:
& I might update you at the flat colors stage, just to make sure I got the colors right. :)
