Haha Soooo yeah, this is me flailing about in an attempt to design a character haha. The top are the oldest drawings and bottom are the most recent.
I knew from the start that I wanted her to have large straw-like hair. Tossed about some ideas with cuter, more feminine hair but it didn't fit. Wanted her to be a very vain character, but enjoyed the idea that she may not have the actual looks to back it up. So as you would expect she is very self conscious of her huge uncontrollable hair and attempts to hide it under her hat.
Used the more feminine hairstyles for her rival (currently-unnamed-unicorn-chan), whom actually has the looks to back up being vain. Uni-chan's horn is a necessary ingredient in many of Penelope's beauty supplies / concoctions so they fight over it all the time.
As for Penelope's outfit I had NO idea what I wanted her to have (other than it being a bit revealing *hides*). But I'm pretty happy with what she finally ended up with.
So errrm yeah there you have it! The end!
