Yes the pots and the angles do look very attractive and give some effective triangular shapes forming a "Z" of interesting lines - amazing what you can see out of a back window!
I am not sure about the red pot - on one hand it is so different from the others that it looks a bit out of place and yet, on the other hand it could be seen as contrasting well with the others.
I would certainly try to clone out the wires coming down the red wall and looking as though they disappear into the second chimney!
The overall slight softness is probably because you had to shoot through glass although sometimes preparing images to post degrades them and this can be remedied. Willie is the man who can explain this!
