Added more layers on clouds

This is the first photo taken with a new (used) Nikon P520 I recently won through eBay bidding. It's quite huge with 18MP of image.
Anyhow, I spent a lot of white to put more layers on the clouds. Since I haven't adjusted much of the values on the ridge the edges are still quite sharp. I need to wait a while until the new layers become touchable before I can adjust those values and colors.
