Nice shot. You know, though it is nice, you might loose the in-focus bottom portion of the shot. Technically it is interesting, but the real interest is the out-of-focus trunk and fronds at the top.
This is an excellent shot. I like the shallow dof; the detail of the trunk provides great foreground interest to anchor the shot and the rest of it being oof teases the viewer and turns this picture into a work of art rather than merely a record shot.
