So after getting FE Prime in the mail, he's easily replaced my RID Prime. Instead of just selling the RID Prime or having two Primes, I decided to repaint him to Nemesis Prime. I decided to add the teal lines to him like the Takara AM-25 has when stickered; lines are done with no guides.
Paints used (all Tamiya): XF-1 Flat Black, XF-5 Flat Green, XF-28 Dark Copper, X-7 Red, X-10 Gun Metal, X-14 Sky Blue
I also hand paint all my figures, no airbrush.
I haven't done photos yet in alt-mode. But all the figures he's posted with here are completely repainted or slightly painted, except the FE Prime.
