Hey there. Nice concept you have. The way you colored it makes it seem like a disney cartoon one too hehe. Ok so here are some things I notice base on your concept. The model's cheeks are kinda puffing out and to the lower part of it, the area seems pushed back so the cheek area and side area faces make it seem like shes smiling unlike your concept. But i dont know, maybe youre working on that right now. But good job! When i finish my other projects I will attempt to create a woman too!
