Is this a case of poor-voter-monitor-calibration? To me it is very dark. Perhaps a building and some bushes in the forground - maybe hills in the back - the bank of clouds might be interesting if I could see them. This shot needs some post processing editing to bring up the contrast and maybe improve the colors whichare an uniteresting brown - maybe bring up some of the purples that hardly show?
The foreground detracts from the sunset here, and having the hill as the backdrop doesn't do the sky justice. Also maybe looks a little overexposed. Beautiful clouds though.
