Graceful Assassin~
>< My screen resolution isn't the same size as yours... So I'm just going to visualize in my mind that the background's width really does fit properly. ><;;
I like the colors and fonts for the section headers... they flow nicely.
However, I don't like the credits at the bottom... because they are a different, non-flowy font and seem to be over-glorified by having a lot of space all around them...
Also, the playlist looks very... not... matching. I would try changing the color, either to purple or gray so that it doesn't throw off the pretty pretty background.
EDIT2: And perhaps extend the width of the player so it nearly touches the sides of its box, like it does the top and bottom (so it fills the whole box instead of just being stuck in the center).
So, er... 8/10.
EDIT: : ) I do think you're doing well with it.
