Mucho Practice-o

Lots going on here  This be a a page of character concept and anatomy practice and consistency practice as well as me dabbling in a different style that i saw one of my friends doing. the one on the far left was supposed to be more of a chibi but i failed miserably cuz i can't help but draw figures as i think they should 

The character is Dannie (i think thats how its spelled) from a story my friends and i are working on. She's supposed to be a bit of a hooligan and a tom-boy so if you guys have any suggestions as to how i can get that message across id be glad to hear them 

just a concept sheet, really
