A good attempt and the colours are wonderful but overall for me it's too dark.
Nearly 1/2 of the photo is pure black. This photo, the way it is now would likely have been stronger if there was more detail in the foreground (taken 15 minutes earlier) OR if only a small element was silhouetted against the sky.
(instead of a mass of black)
You could try cropping into the bottom by 40-50% - that might help as well.
Hope that helps
