Effort: 1/2 - Handful of layers, not too much done, I'd suggest checking out some tutorials, or downloading some PSDs to help you get better. It's a good start, but needs a lot more.
Look: 1.5/3 - While it's not bad in terms of concept, it's lacking a lot of things. Render effects, stock work, lighting, the works. Like I said, check out tutorials, you'd be surprised how much they help.
Creativity: 1/1 - Sure, this is basically a gimme point anyways.
Total: 3.5/6
Overall: 4/6
