This is another theoretical inspired by a picture from Ina Wong on deviantart.com. I haven't looked to see what the backstory of the picture is, having been directly shown it by a friend on a chat server. It is quite a beautiful work as you can see.
Also, the artist is
http://inawong.deviantart.com. She's an amazing artist and does do commissions if you are looking for a book cover or something similar.
As to the question of how to build this character, we have to look at the picture a bit. For one thing, the character is dressed only in what appears to be a nighty. This could mean that they were ambushed and had to defend themselves from the surprise, or it could mean that they eschew the use of armor. In either regard, the character's is clearly very skilled at combat. This makes my thoughts run toward Fighter, Barbarian, Blade-Warlock, Paladin, Kensai Monk, Valor-Bard, Blade-Bard, Ranger, Rogue, or even Bladesinger Wizard.
I am going to dismiss Rogue as there is a very in-your-face style to her attitude. While that doesn't necessarily leave Rogue out of the equation, it points more towards other styles of class. In addition, the yawning seems to give very much an impression of "This is boring. You're no challenge." Again, there are rogues that would fit this, but this feels more like a stand-up-front-and-take-it sort of character. For similar reasons, themes that don't necessarily conflict but don't point to them, I am going to remove Ranger and Bladesinger Wizard from the list of possibilities. Blade-Bard also gets dismissed as that is a path that operates using two-weapon fighting.
I've also already done a
vampyr warrior using the undying warlock,
twice in fact, and while this character would be significantly different from that one, I don't feel like revisiting that version of the undying warlock especially when I have so many warlocks at the time of this writing already. Similarly, while I've played paladins and monks who had similar attitudes to the one in the picture, it doesn't feel right either so I'm going to leave those off the list.
I'm leaning toward this as a sort of Dhampir Barbarian just for the amusing disconnect. That said, I already did the
other Ina Wong picture I had built as a Barbarian as well. While the image of this character seems to be one of doesn't-get-hit rather than takes-a-licking, there's a couple of ways to account for that. Primarily this is because hit points are an abstract that also include some degree of dodging as well as the fact that this is a dhampir so it might just be the scars heal faster than they appear despite the HP dwindling. Though her clothes are not torn apart either, unless she started out the fight wearing more than that. But despite that bit of stream of consciousness, I'm going against barbarian because the lack of rage in her expression. While I've seen the rage represented as cold, pure focus or a supernatural invocation of power rather than actual anger, the bored expression counts against all of those.
Down to Fighter and Valor-Bard and I think, just because of that sheer force of "I'm bored." I'm going with the Valor-Bard. Also, I've done a fighter dhampir recently and while that was a
gunslinger, I'd like to try something else here. This might seem to be slightly stepping away from the idea of martial excellence, but the Valor Bard sits on scale with several of the martial classes in terms of ability and one should remember that the large majority of the population are non-classed and have proficiency in only a few limited weapons and skills.
Similarly, I am going with a Nobleblood Dhampir here. As I'm getting the feeling she doesn't usually invoke much fear unless she wants to. For background, none really stand out for me. I'm torn between Noble and Entertainer. And I think I will go with Entertainer.
