Effort: 2/2 - Definitely enough for full marks here.
Look: 2.75/3 - I think you've got a good start, but with a few tweaks it could be better. First, I can't say I'm a fan of the text, and second, I think this could really benefit with a slight grunge texture to work it all together. I do like the render effects, lighting, and coloring though.
Creativity: 1/1
Total: 5.75/6
FINAL GRADE: 6/6
