Looking good.
I dont know how 'cartoony' or 'real' your looking to make the action, but on the roundhouse kick, the body should be more vertical, but it isn't much of a problem. The knees chamber position though should be higher and closer to the body, and atm, the kick just look like a swing. Insted the kick should be straight and snap back straight into the chamber position as he spins around. Not only does this give you more power when executing the kick, it look more powerful.
Like i said though, if it's a more cartoony action, then it dosent have to look as realistic as i explained, but as the essence of cartoon action is just an exaduration of real life i'd though i mention it.
Yeah, but no but yeah but no....
