The facial structure in that 17 year old Doffy's pic looks different than his other pics through out the manga. Oda usually doesn't change character's appearance that much even after years. Also, the younger Doffy's pic has two earrings but I noticed him wearing only one earring in the recent chapter, so who knows?! :P
