Not bad, Not bad

I really like the colors in the last one, but I like the effects and stuff more in the B&W version without the tech stuff
also, in the one with the tech brushes, there are some things, and some different contrasts that I miss in the others
I'd say:

Remove the B&W layer on the second one from below, bring some fx from the tech brush version, and you will have a pretty good tagg
