A bird in flight

Not sure which forum this one belongs to, but here it goes anyway

I was trying to get close to this bird but it flew away, however was able to track it's flight a bit and this is the result.

Canon 40D, 100mm lens.

Comments and feedback always welcome.

Probably belongs in the wildlife forum, but I like it! And I wouldn't have seen it if you put it there, so I'm glad it's here
My only critique is how centered the bird is, but I like the size in the frame (I think cropping to put it off-center would lose that perspective). Any others turn out well?

I like it, but if you can crop to fill the frame a little more, that would really accentuate the bird a little more.

Definitely play with crops of different ratio frames and different positions of the bird in the frame. 16:9 is fun to play with.
