The drawing style is very whimsical and pretty. There are some flaws, but when it comes to pen art, there likely always will be, unless you're Hayao Miyazaki (he does his manga simply in pen, no pencil). One of the things that's really hard to get past, though, is her chest, which seems to be coming out of the bottom of her ribs. Typically, the bottom of a girl's chest will be one head-length down from the chin. Hope that helps a bit ^^;
