Here man, i took it upon myself to do some edits to show you what i meant.
I shortened pikachu, i took out some hair from misty, (i made it less prominent) and edited her pose so it was more lady like. Then i made brocks hair look a tad more natural. I used the darker brown to make it look like there was more curve, and edited the sides so they weren't to straight. Hope you don't mind i did this!
