Definately better than before. I think it's a little too bold and you might be right......a little less saturation might be better. I think that the with PP you shouldn't be able to tell that it was edited......that's unless you go all out for a really different look.
I also think a tall crop would look good. Maybe the entire height and for width to the right side of the dog and left side just to the left of the tree. Might see how it looks like that.
Yeah, that is some good PhotoShop work for sure! You should crop some off of the left side (and other sides, just not as drastically) to close in on your subject a bit more. Good colors and exposure and focus. Nice shot. And good PS work!
