Waaah!!! It's The End!
I like it, but... Oversaturation galore. Too many competing vertical elements: the two trestles, sign, power pole, light pole, more power poles, mountains. I'd try to simplify this so the impact of that sky and the trestles has fewer distractions, assuming that's what you're trying to convey. I don't know enough about PP to make any suggestions, but there must be a way to keep that acid sky while desaturating the other elements back to normal. Anyway, those are my thoughts.
