|This is almost unfair; piglets are the crack cocaine of the cute farm animal world, and add a muddy face and trotters? yeesh.
Well, cuteness, absolutely. And again, the eye contact and the connection with the viewer - he's going about his piggy business when he notices a guy with a camera? It's that perfect candid moment of contact without have to deal with an upset person. Lighting is strong but you avoided harsh shadows on the subject, so it's ok.
You have a busyness and distraction problem here; the grass in the foreground ends up being a significant feature by virtue of its color, but adds little to the shot; similarly the deep background doesn't add context and takes up a lot of visual space. I'd suggest a tigher crop on the bottom, top, and left, if you have the pixels to do it.
Of course, shallower DOF would help too; but unless you have your ND filter that's hard to achieve at high noon on a sunny day.
Very nice pic, thanks!
