Blueee~ <3
My glee at seeing blue aside, I love this! It's very simple but also cute and those butterflies are love. The thing in her hands doesn't really look like jelly, lol and I like the title of the wall written on her pendant.
I think some lighter swirls in the back could be added, just to make the wall more catchy. Oh, and I think you forgot to draw the rest of her right boob, just beneath the spot where her arms are starting to divide... XD
Other than that, this is so pretty and I'm in love with it. Nice job! :3
