Excellent! If I may critique just a little bit...
Patton at this point in his life would have been - late 50s, early 60s (?). Really I'm not sure about exact age, but probably somewhere in there. Anyway, in my opinion the flesh of his face looks too pink and youthful. Also, not enough sunburnt. He was spending a lot of time out of doors and would have had at least a medium tan as a result.
all the best,
Dan
