I like everything else but the effects overflow on the background. it looks over sharpened allover and it should be blended from some parts. Like Lockmonster said, it now looks a bit messy, since some colors point too much out when so sharpened and that for looks "messy". Yes, it needs a bit more depth and flow.
Also by having softly blended render and so hardly pixelated background, they don´t go so well together.
I liked the last one more, but I´m not saying this one is anything near bad.
I think by your skill level you should also have designer rank ;F
