i agree with zach on this one.
first off, the black text on a gradient that goes to near black ... horrid for the eyes. i would drop the reflections, drop that purpleon the main background, resize your HUGE buttons, never use a cream colored glow on a purple background (or even use a glow for that matter), oh and what is up with the seperator line you are using? i would go with something a little more geared towards your color scheme so it doesn't look like it blends in the 1/3 and 2/3 mark with the color in the background.
i like the purple of the logo on the grey, that was a good touch. i like the rounded corners ... but for the current colors and layout ... doesn't work.
