dude you should just give up. this shit sucks. you have no talent and should tear up all those ugly scribblings, then go beat your head against the wall until you get all delusions of ever being artistic out of it. your character designs are ugly, not thought out at all, and it's painfully obvious you weren't even trying when you made them anyway. Certainly don't attempt to incorporate backgrounds or experiment more with fluid movement or different facial expressions. Just give up.
