Swans in flight

Caught these mute swans flying over the field as came home. They have been roosting in the turnip field nearby for some weeks now.
It was a poor shot, hastily composed - grey light, overexposed because I compensated too much etc etc.
So I thought I would have a play in Illustrator. Not sure if I like it really but don't have time now to do anything different. Have a couple of hours work to do tonight so will catch up on comments later.
