Would give this 5/5. but as the scene needs quite a bit of optimization (unless you got a super beefy PC), I must remove 1 star. The main problem is the number of lights. It should be toned down to 3 (maybe 4 with a directional light) at most being, if needed, moved around and adjusted. The rest are just wasted GPU resources. With that said, except for the issues with the optimization, these scene are great!
