My two mains have gone through some re-design hell, haha. The oldest picture I have of them is a cropped screenshot of the very first attempt at a comic I made with them:
Uni originally had legit rainbow hair (think rainbow dash from mlp), and Raul was a ginger, haha.
They now look like this:
(Raul's skin has gotten a bit darker since this was drawn, but it's a good example picture, haha.)
I like to think it's a nice improvement. :,)
