I love how you've improved the colours and textures. That makes me fez pleasured by the "after" one. Other thing I want to say is that it looks that you're finding your own style The "Before" looks a lot like manga, that cliché mangas/animes. It's a lot like much other drawings. Not saying that is bad, just... it's not so original.
I like your style now, it would be great like an illustration of children's books ^^ really, it's very cute!
