I can't honestly write much here. The game size itself was impressive. I see that most of the models was purchased, so that takes a bit of the wow factor away, but you still were able to create entire environments that felt lived in by these elves. The game sadly was just too much for my machine. I would honestly look into LOD (level of detail), baked lighting, texture compression, mipmaps, and culling. This could drastically reduce the GPU and CPU loads.
I streamed it here but sadly the gameplay is rough to watch lol:
