This was a 4/5 shot for me. I wound up giving it a four for the following reasons:
- With bird shots such as this I believe that head and eye should be in sharp focus. This is not quiet the case, it is a little bit soft.
- The blurred leaf and branch behind the birds head further softens the apperance of the head.
- The colours are a little flat. That is to say there is nothing which gives the image 'punch'.
- Technically it is not a shallow DOF. The bird is in focus and the tree well behind it is not. just being picky, though.
In terms of improving it - I think the full branch across the image and through the bird is very distracting. By this I mean it draws attention away from the bird.
