While I agree that the smaller the scale, the higher the contrast needs to be, I don't think Mike has gone too far on this one. Looks about right to me, but I like contrast and for a figure to pop, I'm not much into the 'duller' painting styles.
As for critique, his right side of the face could use some better transitions, you can clearly see the lines between the shadows/midtones/highlights, this is easily fixed with some mixes of your various tones painted over the transitional lines very diluted. The ears could use some more work as well, look pretty plain, and not many midtones. The nose could also use a little more attention, shading around the nostrills, anf hi highlighting the nostrill tips as well as the ball of the nose. A touch of color under the nose is always a nice touch as well.
I like the view of the face from the front, looks really pretty good. The highlights are especially good. Also like the color selection for the tunic, they are very much in harmony with eachother.
Way to stick your neck out there brother to help get this forum started off in the right direction!
