ASCA Cloud Textures?

In ASCA, I have all 4 boxes Ticked-structures and such. I also have it set to envtex sky textures only. Is this a big deal? Or MUST I turn off the ASCA sky textures? I’ve liked my results thus far (see the imho-AMAZING screenshots) but if I can improve by tweaking this, please advise

EDIT: I do have the clouds on via ASCA-I had understood that they were better paired with the Envtex sky textures. So all 4 boxes are ticked in the ASCA settings-I wanted to make that part clear
