Mockup's Tweaked

I've tweaked my designs slightly from before, I've tried to make them a little clearer and the chat box is less transparent so you should be able to see it on every screen.Ive also experimented with a white stroke around the nav buttons instead of black. I'm aware there may be too much colour in my designs, and perhaps I was trying to copy dizzee too much so I may have a look into dumbing them down a bit. Chris seems to have it pretty nailed and Liam's is very clear.
