Nesting Goldfinch

We have a couple of nesting Goldfinches in one of our trees, so I grabbed my D700 and a 150-500mm Sigma lens and managed to get this shot. Depth of field was a problem, so I tried pre focusing.

I am new to this type of photography so any constructive criticism is most welcome.

It looks nice, but why such a small image ?

Am I not limited to 97kbs per image? The original is over 6 mega bites...

very nice european goldfinch image. you can always save the file at a lower compression setting at 600x400 and link from photobucket or another image storage site.
