You say it is not your best shot, but then it is not bad either. I like it. I find it very hard to catch birds in fight, you should be proud of yourself.
Not your best shot?
Well, I have finally scanned the only hawk photo I ever managed to get so far in all my life, and I will post it in a thread of its own just so you can get a laugh
Well, my thread is up now for you to laugh, it is here http://www.thephotoforum.com/forum/showthread.php?t=35045 and I think I'll add my two crow pics to that same thread, so you can laugh even more! Nothing comes close to what you call "not the best shot" then....... believe me!
