Nice effect, but the structure is off..
The colours are alright. It has that sorta thermal camera look to it, which is fine, but it needs a bit more structure if you're gonna use that effect.
I think that the bits of red are too small and spread apart too much..You would have been better off with 3 or 4 large patches. There isn't enough blue to make it worthwhile either..
Maybe you should try doing something figurative in that style
