Thanks for the feedback, folks!
regarding Cortex's coat: I actually tried to go for a lab coat idea... and then, when he became a welder, it was more like a shop apron... but i can see dreadnok all over him, too -- like DTC Monkeywrench... which goes against what i was trying to do by painting the hair highlights white & glasses black...
maybe i just need to try and fashion a more apron-ey apron?
pluv, i thought about trying to paint over the yellow to get a more uniform yellow... and fear won out. i saw it forever turning into a 'paint yellow, paint red, paint yellow, paint red' scenario... so, i just let it be "of a different material"
...
also, the purple in the gold you see 'coming through' is actually purple on top... i didn't do a good enough job of washing out my paintbrush between touch ups...
i think i'll give that silver -> gold paint app a try before submitting it to the archive...
maybe i'll try that on the yellow crown, too...
thanks again, everybody!
