My eyeballs almost exploded when I opened this.That water is perfectly still! The sky looks amazing (twice), but I think this image might have to be viewed LARGE, as the way I'm viewing it right now (IPhone 4), it's super busy with a bazillion focus grabbers that have my eyes jumping all over the place.
Right off the back I noticed the dirty sky = dirty water and very grungie/grainy. I dig your back yard but I would have to agree with dominantly on this that it is very busy. Also lacks sharpness.
Not horrible but, I think you should give it another try.
I appreciate the comments. I do have the beginners tendency to overcook the HDR. I know there is more that can be done with this in Photoshop but right now the only post process software I have is Photomatix. I will get more software as funds allow.
Here is a slightly toned down version
Sharpness is certainly an issue. Picture 1 also has a tilt issue. Out of the two pictures, I much prefer pic #2. As for a dirty sky, I actually like it and it's reflection.
