Great idea. I was just thinking about a vampire Tony Stark in an Iron Man armor with blood extractor kits (one with sterile needles, table and orange juice dispenser for for willing donors field extraction and non sterile one with immobilizing devices and sedative injectors for non willing victims) and its advantages to cyborgs or whether vampires drinking their own blood increase their powers quicker (because Dracula in Stoker forced Mina to drink his blood, and Anne Rice's vampire Arman made Lestat immune to sunlight with his blood). A surviving vampire in a science fiction like GUNM/Battle Angel Alita would be a very great idea, just like the cyborg clown Alan Gabriel in The Big O anime. I also like your computer airbrush technique here, including the perspective on the feet, but don't feel confident about my tablet skills. A very great work, both in concept and techniques.
