I really liked your shot of the bird and I did an edit of it, I hope you don't mind. You can see it here. I thought it had alot of potenetial and was just abit too bright. It had lots of detail in it and I think you did a great job capturing the bird. I listed all of the steps I used and if you have questions feel free to ask me. BTW, I was one of your 6's.:)
The look on its face is terrific and your focus is great! If you have room, I might crop it a little higher to drop some of the log and add a little more space around its head.
i'm not sure if it's the bird, or the position you were in, but he appears to have a very oddly shaped head. unfortunately, one of the more immediate things you notice is that his bum appears more in focus than his head - probably the result of a low f-thingy - which lets you down a little bit (especially the softness round his left / our right eye). though the depth of field does give a nice background which compliements the colours of the feathers, and the grain / noise is a pleasant effect. the best thing is the expression on the birds face; almost humanly grumpy. and this makes the shot more characterful and endearing than the majority of nature shots, and makes it stand out for me. a bird with personality scores highly in my book; so 8.
Maybe could have used some contrast/level adjustment, and noise reduction. But the composition is excellent and I really love the bird's "expression" as he is looking at the camera.
