The displacement on Half Dome is very extreme, so not "realistic" (in terms of what it actually looks like), however the lighting is phenomenal, and I quite like the image in general. The outcrop on the lower-right is great. I think the scales may need to be shown even larger though, it's quite a big area, maybe more haze to the background, or perhaps it's that the clouds have this look to them that suggests they are smaller than they should be. Clouds going out to the horizon, that would be some 30+ miles away I think, so they should perhaps be smaller. Are you using the real-world scale of the DEM here?
