Just a note.. Most of the 'killer' shots you see on this forum are as a result of post processing and not because the superiority of the camera and or lens.
I have all my settings adjusted to be as neutral as possible... If I view a JPEG or RAW file right out of the camera, they aren't much to look at..
I adjust the contrast, sharpness, saturation etc. all in post processing. Then they look like something.
Also..
The EXIF data in most of your photos shows 400mm @ f/5.6.. If you're using an EF 100-400 lens, you probably want to get closer to f/9. On really distant shots, the lens is much sharper there.
