Nice shot! Have you had a look at it cropped slightly on the left to bring the tree onto the thirds (left) and also cropping the tiny branch on the right hand side (middle). Just my 2 cents.
Seems you have a couple of people interested in the grip. I am interested in the D90 at your offered price of 650. Perhaps you can put two people together to do the deal?
This is the one I ended up with. I called it “Banished” as the red one has been sent off for decking the blue one (pun intended hahaha). I liked the idea of it being a mirror ..but not exactly a mirror. That is why I cloned some of the chairs out, as I think it looks a bit obvious if it is all symmetrical. I guess it would work as a B+W but for me I wouldn’t do it with the chairs as an exact mirror. You can perhaps see why I cropped the back trees rather tight but I kinda had to leave them in too…they don’t really bother me that much though.
