I think those two are actually pretty nice, Bicep looks much better here than in the instagram posts surprisingly. They're not as striking as some of the BG villains like you said, but better compared to someone like Bulldozer although he's starting to grow on me
and the literal-whos here and there. Designs like Incinemiau and Konan are legit fucking awful though and Eflora was very dull. I think whatever newer character designers they have aren't putting the same 'spice' in these guys as they did for the side villains.
