It's quite interesting to see how the way you post-process a photo gives you a very different result. I edited a similar photo about a half a year ago, and from then I changed my post-processing steps completely. And the result is a completely different HDR photo :)
Photo taken from the Three Towers in Bratislava. In the photo the Tehelne pole (Brickfield) stadium and the New Town in Bratislava. HDR from three shots, taken with Canon 450D with Sigma 10-20mm lens, from a tripod.
