This is a fun image, but a low angle does not make for a topless image. The top is still assumed to be there. I would have liked a bit more contrast here, something to push the image out more.
Did you try this in black and white? I've seen some shots of these trees that kick like that. Also, the composition is a bit centered I think. I like the reflection, though
I think there is a fundamental differencen between photographing somthing topless and not photographing a top. Is this tree topless or did you forget to photograph the top? I can not tell from this picture. (5)
