Don't really like the first one, the flow is wrong. I quite like the second one though, left side could do with a bit more. The third one has some really nice stuff going on in the bg, I just don't like the sudden change between light and dark
First off what is the GR definition of 'blend', second what is 'simple, third flow does not not mean top right to bottom left. It can be a wave so long as it has an intentional direction. Thanks for the crit Fuze.
