Training Ball & Sci-Fi Env

Description: I have two models that need to be made for an indie game I'm building. The first is a simple orb thing that levitates and will shoot lasers. The second is a temple training like facility. Software Inventor 2016 convert over to Maya 2016 Orb: I'm creating a game that needs a sci-fi training orb that'll levitate around, and fire lasers. I've done a very crude sketch (attached) to help you understand what I'm envisioning. Temple Environment: It should feel like a wide open space that also seems a bit "sacred". I've provided another crude drawing of what I'm envisioning. I have a couple of tweaks about it though, I'd like the ceiling to be much higher and there to be pillars holding on the lights instead of them just hanging on the wall. And the windows to be about 75% of their thickness and taller.
