It's one thing if you commissioned the piece. Thats a good-looking sketch... I see where you're coming from, but it's less about how regal you look and, imo, more you appreciating the art and the favor - remembering the moment! It's no different than framing a holiday moment from a disposable camera where you happen to be favorably pictured.
I obviously still think it's so good that you should frame it, haha.
