Good capture and concept. I would like to see it maybe worked in a way such that both Capivara or whatever are more distinct, at the whispering point there is some lighting issue that I am too novice of a photographer to tell you how to fix...matter of fact I this comment isnt really helpful, but Ive come this far and I must say those are some nice pets you have there.
I used to see boars like these all the time in Germany. I think it would look better with a tighter crop. I don't like how the boar on the left has his/her behind cut off. They do look like they are whispering to each other. "pssst, don't look now, I think that person is taking our picture.":-)
