sugar - love the simplicity and directness of the design. If I could make a suggestion, it would be to have an arm of Dracula's wrapped around the girl.
Zinc - your version reminds me of John Carradine's portrayal of the count, which many regard as the closest to the book's decription.
Sinistral - the glint in the eye and the blood red lips hint nicely as to the true nature of what might otherwise seem a respectable gentleman.
Gunsing - there's a real feel of the era in your portrait. Other than Gary Oldman's portrayal, the manner of dress also put me in mind of Fallon from The Prestige and famed horror/fantasy expert and author Kim Newman.
Kodabble - Nice pose. It's like we've stumbled upon Dracula with his latest victim, and we're now ourselves caught in his hypnotic gaze.
Gabriella - I liked the original sketch, even if it was very influenced by the Gary Oldman movie (which is a visual tour-de-force), but I like this new one more. There's something both classic and modern about it. Interesting piece of trivia - the canine vampire fangs, which are associated in most people's minds with a classic vampire, didn't appear until the Hammer movies with Christopher Lee.
Disco Matt - he looks regal and creepy, as a good Dracula should. It would be interesting to see how you handled the brides (oo-er), but what you have is a very strong image, and probably better suited to the challenge.
Sonofwolfhound3 - A nice, sly look, and I like the grittiness.
