Yeah it's a super slick edit. I'm not even into CS and I can't stop watching it.

I've done like 30-40 frames but just displacing the layers a little doesn't appear like a trail as you can imagine so I tried moving them back a frame but that doesn't look quite right either. I'll post it here tomorrow because it's got me stumped.
Other than that though it's worked fine and was rather easy, just time consuming.

Thanks a bunch for the help mate ^^
