...IMO the edit is very good, but...
he doesn't seems nigger enough to me... 
What the hell man. 
I figure this was a bit of a linguistic misunderstanding - if I'm not mistaken, Ulisan is Brazillian, and in portuguese "preto" is the word for "black" regarding color, but is less respectful than "negro" when referring to race - however, that sounds a lot like an english word which is more offensive - even though both words probably have the same etimological root, their connotations turned out quite different in their respective languages.
That's just an edit of guile. 
From what I recall from Caddilacs & Dinosaurs, Mustapha didn't have particularly flashy-looking that would justify making very distinct edits...
Adding a cap and sleeves to everything and making it all look right is still work...
The one thing I'd point out though, is that in these edits he seems to be wearing a t-shirt instead of a shirt.
