I really like the image and love the mood of it. One thing, does the leftside look lower than the right?

Thanks for the comment. I had straightened the roof but felt the same way. I think I need to straighten the base of the house.

I just thought the photo would look better at leveled at the foundation instead of the roof. Thanks for the comment and viewing.
Rooflines sag and houses settle, so its very possible for the roof and foundation not be level to each other. I worked in an old house 3 weeks ago from front to back this house was out 18 inches, I am serious if you put a bowling ball down in any part of this house it would smack the back wall with force.
Bruce - I don't know to what extent the name varies depending on the software you use. On the GIMP it is the Perspective Tool that you'd use for this function. Basically, if you think of a square or rectangle, the tool allows you to drag each of corners of that square or rectangle independently. By clever use of that you can get things like roof line and the ground base line lined up (or not if that is what you want to achieve).
now with a tighter crop.... fixed.
I think elements has a transform tool that will do something like that.
