I'm going to muddle on for a moment, not sure I can really express what I'm thinking in the right words for description...
This one: the shadowing on the house looks more natural/less processed and allows it to stand out from the sky & ground a little more. Makes the house more of a whole object within the image, with a sky, and a foreground.
I find the processing in the other one collapses the overall objects so it is an image of one thing - contrasty house, sky, and foreground with very similar textures - nothing really pops out as a distinct item and you have to take a moment to pull out each item mentally. That being said, I wouldn't mind seeing the other one on a larger scale - I'm sure it would really draw the eye around given all the smaller-scale contrasts. The HDR halo around the house is noticeable, but I've never really done them so am not sure how to fix that.
I'm guessing the the foreground + front face of house being approximately same colour + highlight levels is getting them confounded with each other during the edit process? IE, any mod you make to one will automatically change the other and you can't draw them apart without getting into more-than-basic post work and cutting them into separate layers. Just had that a few weeks ago on some portraits I was doodling with...
The image is not a true HDR which requires multiple exposures. But PS does have tools that allow one to make modifications like this. It is not my preferred method of processing, but it does have applications. To me it is just one more tool that can be pulled out and used when required. Personally, I can't decide which one is better. They both have strengths and weaknesses. Maybe it all depends on what one wants to achieve as they both achieve different things.
I like this version a little better--it's a little brighter all around with clearer detail--sharper, but that's not to say the other one is not good. I think it all depends on the mood you're going for. The original has a scary, doom and gloom feel to it that makes me want to walk a little faster past this place and the viscious photographer eating evil spirits I'm sure are watching me from the shadows and the new version makes me want to investigate a little closer to find out a little more about the place and those who built and lived there.
I don't know if that helps any or not, Wayne just my thoughts. I like them both but for different reasons.
I think I am partial to the mood of the darker image Peter, but I too like the detail in the later version. I have used the process fairly often now and it adds an element that I like. I have not tried, but I suspect that I could get a compromise between the two that combines elements of each.
