Well this was different. I did like this one but it has a comedy to it. The way you have drawn it really brings out that anime style of humor. I love the sparkle on the smile and face and the background is simple but work out well. I just wish this had more textures and layers going on, it is a simple vector type but I'd love to see what you can do with textures.
