Nice! I was just looking at the Tweedle-twins when you posted. Cool.
What is that flap of cloth across his chest supposed to be? I have his belly khaki and the chest cloth thing red with gold trim but it looks too military/inquisitor for a futuristic gang boss. I was thinking more like the Blade Runner world aesthetic.
Coat I made Chardahon (?) Granite (warm dark gray green) with a cold gray for the cuffs and fuzzy edging. Now that I see yours, I prefer the light bone/stone color.
I know most people don't take mini painting quite this seriously but I try to create an image in my mind and produce exactly that. What usually happens is I give it a go and it turns out okay but I'm still not creating exactly what I'm visualizing. Maybe serious artists deal with this, too?
