The end result is, well, not bad. Your picture has a nice compo that really lets the viewer explore the whole image. The colors resulting from the processing add to the 'construction site'-feeling (orange, brown, dust color etc...). Maybe the sky is a bit exaggerated... It is kinda hard to know when to stop with HDR. On the one hand, it gives some amazing effects, that can be very beautiful, on the other hand, the end result almost always looks the same : saturated colors and unnatural light. Both of them look great, but after I while, people get bored by them. 1 picture like that is fine, 2, 3, heck, maybe 10, but after that... nah, just make good pictures with a nice compo and keep the colors as real as possible. But hey, that only my personal opinion !
