The middle of the day on a sunny day is not the best time to be trying to make landscape images. Lots of judges have said that so it must be true!!
However on this occasion what little cloud there was covered the sun for a time. Every now and again the sun peaked through and highlighted a small part of the mountains or lower level clouds.
The touch of sun then made them come alive.
To be fair it also needed a fair bit of post process work,but the light patterns were there on the day. The whole reason to be a photographer is to notice the light that others don’t see.
