I wish I have the skill to do this. Cool effect
Daniel, it's a really easy effect. Bynx posted a link to a tutorial for the effect in the wildlife forum, then in Digital Art. Once you do it two or three times, you can produce an OOB photo in ten minutes or less.
I hope you don't mind. I did one with your photo. This is just a quick and dirty application to show what could be done. You started with much nicer geese than I had, so I'm sure you could come up with a really special shot from the original high-res image.
