I'm trying to do my best to emphasize things about Eila that make her unique so most of my concepts have their basis in a set of specific appeals or attributes. Those appeals are either enhanced/showcased, changed/removed, or tested.
The first one was emphasis on her personality and seeing if her familiar parts could fit in with modern clothes easily.
Then the second one was to see the extent to which I could change an attribute of her base design while still making her recognizable as "Eila" the character.
I have an infinitely growing reserve of commission ideas to work with. In fact, I actually have 3 in the works right now.
