I like the art. Your battlers have a style I like, one that was prevalent in a lot of the art I enjoyed in the 90's when I was growing up. Good work there, I was a Goth back in my youth (and kind of still am) and the art and colour is a good combination.
Many of your gothy scenes have red, black and white as predominant colours; personally I enjoy that colour combination- perhaps I'm biased, but they are my favourite colours.
I have to wonder, however, why the enemy in the screenshot is wearing a loincloth. I'm sure there's a perfectly good reason, but I would have chosen a different shot for the thread.
I find the title confusing, though. Vampires are typically hurt by sunlight and the use of the word Dawn makes me wonder what's going on. It makes me think that vampires in your mythology are unharmed by sunlight, and that turns me off. Of course, I could be wrong, and it DOES make me want to play the game just to see.
Also, the title's initials are VD, which means venereal disease in modern medicine. Although that is a fine point, and probably one you won't want to change given that this is the third installment of the series, be aware that some people may have fun at your expense for the title.
Finally, I have to ask where the first two installments are. If this is III, what happened to I and II?
Overall, though, this is a project that appears viable- by that I mean, looks like it's worth playing. I look forward to seeing where this is going.
