HDR on the Rocks

I just purchased a copy of Photomatix and now I'm attempting to get up to speed with HDR style of shooting. And so here's on of my first HDR creations. I am shooting with a Sony a6000 mirrorless camera and in recent weeks have been using fine jpg format rather than RAW. I used jpg format for the following picture shooting (obviously) at sunset three shots with +/- 2 EV . This photo was taken near the Big Meadows Lodge on the Skyline Drive in Shenandoah National Park.
