Yeah I've been thinking about add some green. But not so much, maybe a lone tree near the temple, or some bushes. Also, I've noticed that odd black things in the leftmost stone; they look like shadows or something. This may be related with GI surface details, as I haven't activated it for the previous iteration, my GI settings were 3/3.
Any more ideas, crits or suggestions will be very welcome. I'll be working in the next iteration as long as my job and guitar practice leave me some time to do it

Thanks everyone!
