Have あなた ever went through the character development stages of drawing?

yes. My charatcer name X. I had to change her 14 times just to get her perfect. I am making a comic now.

Yes!
My sonic character, Coffie, has been been in a million stages. She went from being an echidna, to hedgehog, to hedge-echidna and finally to a cat

I'm still in that stage. I've got over 4 series that I want to get to the drawing board. I'm still thinking about the plot of each story though.
