Sadly, that is better than ALL of my school's Comp Graphics (even Advanced... people suck ass) pictures.
I however, hate it. Nothing against you, but that is horribly made. The colors to me clash too much, and it's really bright (and my gamma is like, 2 off lowest). Also, the lens flare in the bottom right corner can be made about ~10% less opace (less visible).
Taking into fact that you're not a big graphical guy and more of a designer, not bad. 5/10
