First Go

This is my first go at creating an HDR image. I actually created this out of one RAW file. I used Raw Therapee to create a properly exposed, under exposed, and over exposed jpg image. I then proceeded to Luminance HDR, where I combined everything together. I really like the way the clouds and mountains turned out- but not so much like is given by me to the buildings. Does anyone have any suggestions?

In case anyone is interested in the two programs I used, here are links to them:

They are all completely free and open source programs so you can use them however you like without getting into any licensing issues.

I'm still trying to learn photography even better and hope to move on back to video and film again once I feel I am ready. One must first be good with single photos before they move on to a series of them, creating a motion picture.
