Its called rocky cloudy peak these are mountains which are rocky. Made this with with 2 terrians and with function editor its complex and hard but i am getting used
to it as i suck at sculpting mountains and they don't give real touch. Two terrians were made using terrian fractal and rocky mountain filter and hence it has that strong and sharp peak like a knife and than exported terrian in World Machine and added erosin and clamp and other nodes to give more realistic look. And hence u can see those snow coming down on slope its magic of WM which i love using. And clouds are thick cumulus but have very high variation in between 600 to 900.
Render time 3.5 hours and added DOF and other things in PS.
