Overall, the design looks cool, but, the colours are just dreadful. I love White over Black, but then you have those near 255,0,0 red and 0,255,0 greens, that just make the eyes hurt. Specially the red, since its a colour near the end of the visible spectrum for the human eye, it just doesnt get confortable over Black, just like if you would use violet colours over black, which is the colour on the other extreme. I would change the red to a lighter orange and for the green, I would just stick with that wonderful acid green you have in the logo (both, to offer more contrast).
Inverting the Background/Foreground colours on the Icons, would also be nice to offer more contrast with the black background from the app, or even make the lines a bit thicker on all those smaller buttons. I'd also move the exclamation mark on the left, near to the endorsement star.
I dont understand why the category count is enveloped within a Red/Green circle, looks like its representing some kind of counter that is getting full, unneccessary and unfunctional IMHO.
Its visually more bold and interesting than the current one (which is good), but generally, not very functional for the eye.
Cheers, and thumbs up for going towards a more modern graphic design!
