it's okay!
haha, at first I thought those were Kasumi and Ayane from Dead or Alive, but then I noticed that there's no purple hair on the supposed Ayane. : D
And well, I guess it's okay as far as drawing. Better than what I'm doing, but of course with a lot of potential for improvement. What's pretty good is the shading on the skin. On the hair not so much, though.
Also I'm not in particular a fan of that "shiny" effect on their breasts and cheeks. Makes them look plastic.
