How would you crop it?
When i get on my other pc (Home) - i will give it a go.
All ready thought about it.
1) crop the left tree out - wait ...include the fence line.
2) crop the right building just so you don't see the vertical corner
3) crop the top down just a little (last) - to fit (rules of third as a guide-only)
4) crop up to the shadow on the fence line....
Did you crop this picture? is there more we are not seeing?
