I really like this one Brian, probably one of the best or the best thing I've seen from you. Since you posted it here though, lemme see... first thing is I'd like to see larger, sharper pics to get a really good look at everything.
Overall nothing major, but maybe a little more attention to lighting direction would be good, making the topside lightsource a touch more obvious.
I think the shading of the fur (kilt?) is a touch overdone and lightening the darks a bit would make that look more like a uniform piece.
On the skintones, although they're done very nicely as-is, I'd suggest adding a bit more variation to its colouring - the torso reasonably pale like here because it would normally be covered (presumably) while the arms and hands would be much more tanned as they'd be exposed to light so much more. A little blush around the pectorals might look good too, often see that when someone is bare-chested out in the open.
