Thanks for the comments everyone.
Saurav: Detail 0.9, AA 8, GI 2/4, GISD 2/2
Bob: You can absolutely make the towers in TG2 using the sphere object. Just warp the spheres using some power fractals and maybe a redirect shader and then texture them.
Badger: Not much changed with the tower on the right, just the sunlight postion and the lower camera. Must be because of the additional elements helping with the scale.
