Vampiric Dethbomb

I've been really enthralled lately with this writing idea I've been kicking around since about October of last year. It's gone through some major changes since the first time I thought it up but for some reason it keeps coming back.

The premise is basically this: A story about a fairly attractive female vampire that has a job as an assassin, and is darn good at it. She's also not above using her body to aid her in her missions, however she usually uses this more to take people by surprise. I imagine that it'd be awkward if the person you were trying to kill suddenly gave off a flair as if they were seducing you.

In addition this takes place in a world where she is not the only vampire, but on quite the contrary, there are several hundred thousand vampires in the world. Some are like her, employed in shady businesses, but others are more interested in keeping themselves to a normal life, and obtain blood from underground businesses masquerading as blood donor charities in order to keep from going insane.

This brings me to another part of my idea. Vampires who feast too often, or too rarely on blood eventually lose their minds. They get taken over by pure instinct, and will attack and kill anything alive and devour it while raw. The strength of these beasts is determined by whether they transformed due to gluttony or starvation.

In addition, vampires don't explode or burn to shreds in the sun, but rather have their immortality completely cut out. During the daytime, they are just as likely as you or I to get killed by bullets, swords, gunfire, or even falling off a bridge onto a metal spike. I'm also imagining this taking place in a steampunk western world. One filled with steam engine trains, airships, smaller helicopters and the like.

Currently, I'm imagining the main character looks similar to Tifa Lockhart, concerning her body type, and hair color/length. However, I'm imagining her in an outfit that's basically a cowboy version of Dante from Devil May Cry. (This is the best I can think outfit-wise: http://tinyurl.com/6jbgv7q)

And yet I just feel awkward actually sitting down to write this. I don't know where I want this to go, I just think it's an interesting idea. I just basically found the only version of vampires that I've ever really liked. But for some reason I just don't FEEL that I'm a writer. I don't want to become obsessed with my characters, thinking that I'm all hot shit cause I did something that people have probably done better anyway.

And on the other hand I don't want to grow so attached to these characters that I begin to idealize them and start to grow unsatisfied with real life. Especially now that I've grown to rather enjoy my life recently. The ever continuing battle between what I want to do, and what I feel society would prefer me to do...

And if anyone is wondering, yes the title is a reference to Dethklok. I just had no idea for a suitable title and really wanted to say "Dethbomb" for awesome's sake.
