As far as I can tell, I see only one purple sky.
Again, nice shots, Javier...I am glad to see that you are "leaving well enough alone." I do not do any post-production. Perhaps I should say that I could not do any post production work, as I do not have the equipment for it, and I know very little about it. I try to get as close to reality as I could. With proper exposure and good composition, there should be no need for fiddling around--and this is what I mean when I say that one should try to maximize the potential of film. In my view, post-production may create something that is more subjectively satisfying, but, overall, I think it detracts from the realistic effects that are obtainable in film photography.
PS (for Javier): Before I forget...I received my roll back from Specialty Color Services. The results are fantastic. I have used several different labs over the years, and Specialty is simply the best. I will be sending all of my rolls in their direction. I thank you, again, Javier
