AMazing job, but I think the vignette is too strong, the clay render looks way way better, especially it seems you turned up contrast way too much on first two images, try to increase exposition instead since the images are too dark! The trees shouldn’t be dark stains that way, the details should be visible just like on the clay render.
This is just my humble opinion, I think it would emphasize your fantastic modelling even more!
Congrats

Those renders look nice, there are something weird with the background, maybe with depht of field You can get a better render, it is my opinion.
Good job!!
I agree with elbriga.
Very nice! Although I think you should bring the camera out a bit to give it more composition. Great job though!
