The light on the adult isn't the best, but the begging posture of both chicks is so interesting. Since there's alot going on in this image, I would crop a good deal off the top to really focus attention on the little family.
Love the eye level perspective and the fact that you have eye contact with all three birds. I'd go a little brighter and I'd clone out the twig at the top right of the frame.
Lovely family portrait, great atitudes, lovely poses, nice ambient behind them, and good comp, light is nice although a little more birghtening could help. Congratulatons!
