yes, clouds and mountains are 98% with verve, Kali are Verve and Photoshop, and the Trees and the Gras are painted in Verve, but I did have problems with weird borders sometimes in verve with stamps/brush #0, so I used for stamping artrage
For Rocks I used often Brush #8 #9, at the beginning also #7 - I used also the hidden function with SHIFT + K for selctions but sometimes also lasso selections in PS. For thunder-clouds #4 and #5 and sometimes also #1 & #6, for other clouds I think also #8
