Great jobb, kawaiileena!

They're super kawaii ^_^
Especially the first one.

My advice to you is to study anathomy and (well, I don't know if you have allready ^^') try to draw realistic human bodies. Even if you wanna draw manga, that could really help you out when you, later on, want to exhadurate bodies. ^^

Ask a friend to pose, if you don't have anything else to draw - that can be a lot of fun, y'know *giggles*
(I often make my boyfriend pose for me)

Good luck! And hope to see more of your art in the future!
