Here are some progress shots of turning a TF Classics 'Jazz' car into shockwave.
Test painting + sanding to prevent joint wear.
Replaced cast, and fitted in the arm. Figure still transforms int car mode with gun-hand.
I'm experimenting with Hydroshrink to create a resized version of the original Alternator Shockwave head. If that doesn't pan out, I'll opt for a 'Fall of Cybertron' Shockwave head instead.
The original concept for this as a Classics-verse Transformer was found in an exclusive Botcon customizing class. Other reference art is by Transformer artist Dave Kahanna.
