All right. Hopefully I've fixed the angle issue using your edit as a guide.
Not sure if it's good or not. Also, that purple crystal on the right side is bugging me. Even after looking at a reference image, I still feel it's not quite up to par with the rest of the image. Also, I've left the right side of the platform completely bare because it animates in the game. I'll be trying to animate that to the best of my abilities.
EDIT: Fixed a few minor things about the centerpiece of the floor.
