Hey Tiradia, how are you shooting the bird? or most of your photos? The EXIF is not listed on your Flickr page.
If you are shooting in RAW, not sure if you know, but RAW does not impose sharpness on the images as if it were shot in jpeg. To get the images sharper when shooting RAW, you have to add the sharpness in later in ACR or what ever application you are using for post. The same thing applies to color temp.
Would like to know what your settings were for these and what format too. Or maybe I missed them….
