O.K, let me start off by saying HDR isn't really my thing, so take what I say with a bit of a pinch of salt!
I don't really understand the use of HDR here! I've seen a few examples of HDR that I really like (only a very few mind), and the idea was to capture a higher dynamic range than the sensor could otherwise achieve. This meant no blown highlights, and a very natural look.
However, in this shot, a sizeable amount of the picture is completely blown as far as I can make out, which to me defies the point of HDR.
It looks more like the saturation and contrast has just been put through the roof, and while I like the composition, I think the colours are a bit nasty!
I'd much prefer this as a long exposure type shot, or a contrasty black and white, but these are just my opinions, so please don't be offended!
