Quick question...Lupin was a werewolf...Would it be alright if my character is a vampire? he would be using charms to give his skin more color and also he would be using an old form of magic to create his own blood source...

I do not think that a Vampire would be able to fool Hogwarts's defences. Without special permission, they would probably not be allowed in the school. Is that what you were intending?
