Still a work in progress, but I have the alt mode complete.
I'm using a Blurr body with some reprolabel G1 Nightbeat stickers.
By a lucky chance the blue paint I got was an exact match for Blurr's blue, so painting was a cinch (so far, anyway).
Robot mode transformation is going to be a bit different.....
