#1 for me.
NOT #3 - she needs to edit, too many accessories that don't go together. Where is Michael Kors when you need him? The gloves and glasses suggest a gear or leather fetish. The garters yet another fetish but don't go with the shoes (boots?) or the briefs - boxers would be better. The jewelry is too trendy and the poppers inhaler suggests power btm.I vote #2 simple, nice definition without being too cut and bold enough to show his face and hairline unlike #4 who has a the best bod and I'm a sucker for a man in a cap but I still vote #2.
