I like the pose and the exposure looks excellent - just the right amount of detail in the blacks (on my monitor anyway!). I agree with Ofer about the birds positioning in the frame. I also find the way that only the tip of the twig on the right was clipped off a bit awkward - I'd think about either adding a small amout of canvas of the right so that you can see the end of the twig (with a reasonable amount of clearance to the edge of the frame) or clone out / clean-up the tip of the twig.
