I'm still not sure what you don't like, specifically about the sky. If you are talking about the grain, keep in mind Perceptol is not a sharp developer, so you will not get very crisp grain at 1+1.
Maybe grain, maybe rendering blured sky. This is my first try with long esposures on film. Do you have a recomendation for developer? Could I see your pictures with long exposures or do you have only paper photos, please?

Thak you.
