This is an island inspired by Patagonia. If anyone has suggestions for improvements please let me know!
The clouds could be set to high quality and the samples increased in the clouds quality tab. I would also try more edge hardness.
I find the transition from rock to ice a bit harsh.
njeneb and TheBlackHole, I increased Edge Sharpness from 1 to 2, and increased Quality samples to 128 (from 64), and I changed the snow on the peak (made the snow layer have less coverage, then added a higher snow layer with more coverage). I appreciate the feedback!
What is the focal aperture of the render camera. The field of view seems to be very wide.
Focal length is 8.18435
Try changing the horizontal FOV to 50. You may need to change the camera location. The clouds look very stretched out, doing this will get them to be more cloud shaped.
Thank you, njenab. I changed the fov and did a quick render. There's quite a difference in the appearance. I think the fov was the reason I had such a problem with the water, which was too dark in the foreground, like a semi-circle shadow over the water. I'm going to start over this one, but with better understanding of fov.
default fov should be fine for most scenes, once you start zooming about things can go a bit awry, rather than zooming, I tend to move the camera to see what i want, then if necessary I will tweak the camera settings, looking forward to see how this progresses!
