Peace!! Nah, once i had completed the image in photoshop I duplicated folder that had all the layers inside... Merged down that folder (which was duplicated) into one layer...

then duplicate that single layer double click it and untick the R and B option off and leave the G box ticked. Select the move tool and just tap left or right up or down on your keyboard depending on your taste.

Then that gives it that chromatic aberration / distortion kind of look
