All looks really good, except grass. Lawn should be mowed and grass material could use more translucency. Usually grass is more translucent than tree leaves.
Well done AlexThis renders are soft and clean; could you tell us how you light them ?ThanksRoland
Very nice, I like it a lot.Maybe a less reflective glass would make it look a bit more "realistic"Also I liked the highlight on first image a lot more, bring it back! & downgrade the gamma/exposure a little bit ;)
