I used the same .tgd file here that I used on my last image which was created using 'Schmeerlap's tutorial except I changed the POV, some surface colors and added some autumn trees. The trees consist of three populations, each of a different color using the Painted shader. The cumulus nimbus clouds are from a file from NWDA.
Looks like the climb up Ben McDuff is getting stiffer. "My poor aching legs" ;D

I like the POV. You have done a great job with John's tutorial.
