Well done. Have you made the ears smaller. Because, actually, small ears low on the head is a typically African quality (I never realized that until my mother, the portrait painter, pointed it out). So if you've made his ears smaller, you've made him less white. Okay, I'll cut it out with the trivia now
Looks more together with small ears....I think he just has freakishly large ears to begin with
I'd fix the eyebrows - they look a tad blurry and a tad transparent. Otherwise, superior chop.
