SFW is an illustration of a horse, nothing very special - just the most successful picture of today. Actually, I tried to generate a friend's character, but there was no significant similarity. Maybe we'll get lucky another time. 
In any case, I definitely shouldn't limit myself to erotic content. Expect a similar variety in the future.
