Mystic Jack
If you’re thinking of writing a romantic mystical story, then the desriptions you have are on the right track... but I might tweak them just a little bit, just bear with me.
Okay, so I might switch the hair color a bit... put in some darker brown highlights. Jack will have Electric blue eyes with hints of violet and deep green. You didn’t give an age range so I’ll say he’s around 19 in looks, but is 500 years old due to his vampire side. Jack is also in a school for magically tallented beings, and is learning dark magic, healing magic, and protective magic. He is also learning good magic. His hobbies will include astronomy, music, sports, reading, writing, etc. Jack will probably be a celebrity in his home world. Though he is 45% vampire he does not drink blood, he does however eat meat (not human meat). His possible motivation and drive could be a girl from his school who is 45% werewolf, and is the same age as him. Jack also has perfectly straight, pearly white teeth.
