Ashby, Thanks for that little change. It lets me see the face shape now.
Ok ... I am going to suggest a few more changes but PLEASE know that I can suggest these because what you have done is so excellent that I can catch those few areas that don't quite match yet.
Oddly, it is often the case that the better the carving, the more accurate, the more we can see what works and what doesn't ....
In the Stonewall image, red lines, you can see in the photo that the dome of the skull in the forehead area is wider than the widest point of the cheek bones. You captured that difference in width excellently.
When you raised the forehead on the left side up into his hair line you caught that for this gentleman his forehead area from the corner of the eyes to the hair line is longer than the line from the corner of the eyes to the center of the mouth. Because he is bald there is more skin above the eyes than below.
In the Stonewall B image look closely at how his cheeks fall away from the eye.
Stonewall was an older man so the skin of his face had lost it's elasticity. The puff
of the cheek has fallen into his front jowl area. That's the blue arrow on the photo
pointing up next to his mustache.
Even though his cheek bones are the highest part of his skull the skin that covers those bones and the fat padding has dropped from age. So for him the high point of his cheek is almost parrallel with his mustache. It's not directly below the center of his eye.
Because the skin and fat have begun to sag notice how straight the line is from his
cheek into his mutton chop areas of his sideburns. That should be a very straight line or plane on your carving. In the Stonewall photo you can see the side edge of the cheek bone and how all of the skin below is dropping.
At this moment your carving of Stonewall is about 10 years younger than the photo from which you are working

Your high point of your cheeks is still at the bone area and his cheeks are still defined where they disappear into the mutton chops.
Stonewall B, These are small areas of shadow in the photo that define that drop in his skin. The skull just above the temple is beginning to be very noticeable. That's because the forehead skin is sagging and catching in that area of his forehead.
The brow line is perfect .... DON'T TOUCH THAT AREA AGAIN!!!!! I love strong brow lines
But the left eye needs it's farthest corner tucked down, a lot! Your photo is not a
straight on picture. Stonewall has his face slightly to the left which means this eye corner has to be a little lower than any other eye corner.
OK ... One more little thing ... that man was so bald that he parted his hair very low then brushed the hair on our right side across the top to our left. Then he puffed his front bangs to hide that part ...

So his part means that the hair section on our right is just a tad deeper into the skull.
Now I know very well these are very little very fussy points ... but you are soooo close to having him perfect .... And I know that he is a man who's life has impressed you but at the time of this photo, the one you are working from, he was old, he was very tired and he was a very sad gentleman. It shows in the sagging of his face and eyes.
P.S. The lions and eagles are beautiful!
