this work is brilliant! I cannot wait for the series! just a few comments by me:
the first design you did was better detailed but I did not like the face.
on the second revised design she had too light shadows but you fixed them which was good.
you made another face that looked slightly weird but you dropped the nose and it looks normal again!
it's good to have found this forum since I will have been able to see the devlopment of what seems a perfect series. I just want to hear her voice and see the storyline and then people can comment on what needs improving.
overall: well done!!
