A rough outline of a new project, still needs lots of details, particularly in the groundcover...
It looks very nice so far. It seems reminiscent of Yosemite and parts of the Dolomite peaks. Seeing more color (darker greys, brown greys and some reddish orange thrown in) and some lateral strata would make your mountains stand out quite well. A river cutting through this would look nice, maybe even a small stream might work well. Looking forward to seeing what you do with the ground cover ideas.
Indeed, very nice start. I would lower the camera a bit (the angle, so you slightly more of that dark (pondlike) area. More diversity in grass and flowers, and I would get rid of that large grey rock in the field, though a small patch of nicely rounded fake stones (around a pond or stream) at front would be a nice break. The mountain layout is great.
Excellent! Agree with Dune. Great composition and I like the fin of rock but not so keen on the large flat face - needs a little more breakup/veg?perhaps.
