1st version has more potential, Should've made the right eye + trail the same color as the shapes. More depth could be created by blurring more and adding different shapes in the back. Maybe make white and black also come back here and there in the smudges.
I personally like the first one better, the colors looks like they blend in better with the theme that you're going for.
First one is nice. I actually quite like the colours you used and how it flows. One thing I must say though, is the diamond shape on the far right is too bright and distracts the viewer. It takes the focal point away from the guy in the middle. So maybe reduce the opacity on it. Good job.
