Concept art piece of a vampire

I need one piece of concept art of a vampire. The piece needs to be at least 640 x 480 pixels big.
I want the vampire to be either kneeling or sitting and be drinking blood from a cup.
It can be either full body or half the body (both arms need to be fully in the picture, but it can be cut at the waist. i.e. legs are not required - but as you see fit).
The vampire should be human-looking, i.e. no monster-like vampire - no vampires with wings or cross-over vampire that looks like a bat - human like looking.
The picture can not contain nudity (showing skin is of course ok, but no bare breast or similar.)
The picture also needs to be colorized, i.e. not black-and-white.
The vampire can be either a woman or a man - whichever you think works the best and you are most comfortable with drawing.
The picture does'nt need to have a background. You can have an all black background - the focus should be on the vampire.
I've attached a couple of samples - they are to illustrate the kind of vampire I want and the kind of art style Im looking for. There is one picture of a woman vampire drinking blood from a cup - Im going for something like this. It dose'nt have to be exactly like in this picture (i.e. the vampire could be sitting instead of kneeling, have different clothing etc.) - but something like this.
The final image needs to be saved in some kind of loss-less pixel format such as PNG or TGA.

The concept art is for an indie game I'm working on, you can have a look at it on https://www.instagram.com/vurdalakthegame/. This piece will be used mainly as promotional art for this game.
