Hate to say it but its actually getting worse, you added more purple/pink to it which is good, but now i feel like there's not enough orange/red. Try to balance it. Water looks unrealistic now.

Get Dreamscape if you can, its what i made this with:

You can do basically the exact same thing your doing, but a lot easier with it, except i didnt really bother to make a really fancy render with mine.
