Very impressive and good work ! And special thumb up for a scratch made track ! We need more tracks like that in AC, especially this kind of all racing tracks.
From the improvements to be done, in my opinion, are the optimization of the performances (a bit heavy on my mid-end config), and the darkness of the track which is a bit too strong IMHO. It's hardly undrivable under the forest, even using a 150% exposure.
But 4 stars anyway (to be able to put a fifth one when it will be perfect ;-) ). And keep up the excellent work :-) Many thanks for sharing !
