Beautiful bird - good sharp capture on the head and legs in flight, always a challenge.
I might sharpen it a bit more. Another suggestion would be to lighten the iris with an edited overlay layer. I would
You should do it before resizing - my poor attempt on your small jpeg shows the effect:
BTW - effect is just iris lightening - after posting you will want to do just a bit less than the example(you will have more control on the pre-resize image). I don't think it needs more sharpening and this wasn't done on the edit
Getting a bird tack sharp in a direct approaching flight direction is no easy feat. I can see a bit of noise in the wings though ( ...7D is a pain sometimes) Is this a big crop? Regardledd a great shot of this masked weaver?

I like the OP, suggest a little noise reduction, a very difficult shot to get in focus but you did it - well done. Apart from the noise I wonder if the image is oversharpened, the eye looks granular, I suspect some NR prior to sharpening would help the image considerably.
