Here are a few progress shots of the wip boss arena platform for the Missile Monarch boss fight.
This includes concept art, a shot of the high-poly, progress of the retopo, texturing screenshots, and in-game screenshots
The first image is where it currently sits at it's first texture draft, and the side thrusters will be added later. I'm also not sure about the crystal on the underneath just yet, might just make that the same thruster effect that the Booster enemies have, or nothing at all since you won't be seeing the bottom of the platform except in a cutscene maybe.
