I've never tried a TF custom before, and actually I've always thought of the prospect of doing one as pretty daunting. But I've always wanted a good Galvatron toy based on his G1 cartoon look (The G1 toy looked nothing like he did in the cartoon/movie, and the Energon one was still not quite there...and impossible to find). While the new Classics one looks awesome, and I'll definitely buy it, it's going to be pretty small. So I recently acquired an Energon Megatron and went to work.
I've got the robot mode almost completely done (I had to sculpt the 'horns', since they were missing from the Megatron I traded for), and I'm piecing together his alt mode. I still need to figure out what I want to do for his plasma cannon (I've got some ideas for the barrel, it's just the arm connector that is giving me trouble).
Anyway, here's the WIP pic:
