I quite like most of them to be honest, but there are three that really stick out.
3. I quite like entry 3, The render fits in nicely with the background and the text and "style" of the entire thing mixes very well.
5. Entry five just made me happy to look at, it's fun and unique.
7. The blending, the work around the render, the background and the foreground is simply stunning. It's art, simple as that.
My vote goes to entry 7
