Never seen a shot of a Peccary, let alone a Peccary, so thanks for sharing. Looks like a cousin of the wild boar...
From a C & C perspective, I don't like the fact that there is too much space around the subject. Like you said, a better crop would be nicer and it should be easily possible since you shot with a 1DsIII.
I would take some off the right side so the main bunch of yellow flowers was not so dominate. Wish he/she would have come out into the open a bit more.
He/she did. I've got a few more shots of it at full body. I saw it coming and positioned myself where it came out. Plus one of a Javelina drinking at the windmill that the one in this shot was headed for.
