Whchung has requested an example using wgCMYK, so here are two of them. I hope they will be of interest.
One of the main strengths of wgCMYK is the ability to control shadows without affecting lighter parts of the image, and without changing colors. I started by placing a neutral on the stone area behind the gorilla as a neutral, which I remembered as being gray when I took the image - the curve points for the neutral are indicated by tick marks on the graph. Then I moved the black end of the K curve in to get a good shadow, and make the K steeper overall. I added another couple of points to the K curve to bring out the fur texture some more.
I'd suggest that you experiment with the original image, first correcting it in whatever way you feel most comfortable. Then try to recreate your results using wgCMYK.
I did not use Lab or RGB for this image, and you may well find that you get a more pleasing result in one of the other color spaces.
