Very cute, your style is certainly unique and fresh. ^^ Try studying anatomy, such as bone and muscle structure to help with body shape if you want to. It certainty has helped me. Heck, I sometimes fill up an entire piece of paper with doodle of hands just to improve at them.
Good work, and I hope to see more from you! 'u'
