ohhhhh-mean-mullatto-twin, who complains about skin tone, when her drawings are so dang GOOD!!!! Heheh, didnt' mean that you're mean, but your chibis are great I LOVE D-sama. He's so cute in the second movie. ^_^
Have you tried using a more (forgive me) browney color. Not a tan or peachy one. Maybe using a brown around the edges will help.
I LOVE EVERYTHING ABOUT IT!
