Personally when it comes to exterior shots I go for wider shots than 3x2. I'm talking like 3x1, 2x1, or 16x9. Mostly I like those wider shots because I feel they isolate the subject most for exteriors.
Here's a quick and sloppy little crop at 2x1 I did of your picture. Unfortunately I'm away from my PC ATM so a better crop couldn't happen but I think it shows what I'm trying to say.
Of course lately I've been really falling in love with 1x1 images but that's a whole other ball pit.
Finally got back to my PC so I could do some fun editing
BTW would you be alright if I share this edit in my online album (DeviantArt page) provided I credit you as the original source for the non-edited image and provide a link here?
