I have to agree with what seems to be the general consensus. At least for my own taste, this shot is very over-processed. I will attempt to elaborate, though...
For starters, as was mentioned earlier, it doesn't really bear much resemblance to anything that could be called a "photograph". Without getting into a debate about what constitutes photography (let's not crack open that can of worms...PLEASE!!!), it's rather clear that this shot lacks any feeling of realism. It looks variously like a painting or color-pencil drawing... but not really like a photograph. But, let's assume that you were going for that look. This first attempt still suffers from certain problems.
Take the clouds, for example... they've been mangled by the tone-mapping process. I can only imagine that they were originally fluffy and white... but the HDR proces has transformed them into rather unappealing, uniform grayish blobs in the sky. This largely defeats the whole point of HDR, which is to expand dynamic range. Ideally, you'd tweak the HDR settings to get nicely-exposed clouds AND a nicely exposed foreground. That's not happening here.
Also, there are strange "cracks" running through the clouds. I'm guessing that these are remnants of blown-out highlights in one of your exposures that made it into the final HDR. Again, one of the major drives behind using HDR is to tame wide disparities between light and dark in a scene. If blown-out highlights make it into the final HDR, you're doing something wrong.
Another problem I'm seeing is a "blotchy" blending of exposures in the sky. The sky towards the upper corners has a noticeably different coloration than the portion of the sky closer to the interior of the frame. Ideally, the sky wouldn't have this type of blotchy, uneven appearance. Tone-mapping should be more consistent to produce a result that doesn't look...well... down-right strange.
You want viewers to notice your subject matter, not your tone-mapping. In order to achieve that, it's important to eliminate all the technical flaws that can arise when exposures are merged.
Hope I could be of some help.
