Well, honestly, I hope this stuff is interesting for somebody. I'm always interested in my models being used for something besides their existence, but that hits the question of quality. And a problem is I'm usually slow at my work.
Orca: 9746 polygons + old conic spikes. Remodeled engine and nose, some cleanups. I suppose that 20k is a safe polycount limit for nearly any purpose. And yes, they're septagonal. Actually, that's the way I model it - I model one segment and then just replicate it prior to rendering.
Capship Missile: now 175 times more high-poly and 64 times more high-res. And while model is more or less good - at least I like it - texturing went somewhere wrong. So - top to bottom - original Capmiss, 12 polies; my model of Capmiss, 2104 polies; failed attempt of organic high-poly for AO and normal map baking, 27340 polies; final result with NM and self-illumination applied.
Also a question of style I should follow - game style - nearly polished metallic or art style - with a lot of spikes, horns, uneven geometry? C&C welcome.
