I am not involved in assessing entries but that image does look underexposed and is very over-saturated.
There is very little at the top end of the histogram
I would reprocess from the raw file doing the following :
Decrease the saturation
Rebalance the white balance (it is too blue/green at present)
Then adjust the exposure and highlights and lowlights both visually and key an eye on the histogram (our eyes adapt quickly the histogram does not)
Finally a straightening crop to put the buildings and telephone poles upright.
I hope that helps you
