As I promised to review, I wanted to make sure I'd gotten up to speed on where you were with the story. I shared with you that I don't watch Smallville, so many of the references you had of that show were lost on me.
I think that you have the writing bug, and that you should continue to work with your craft. Writing has been one of the things that has grounded me over the last year.
The more you write, the better you're bound to be -- but the other thing I would suggest is to also read. Read a lot. Fanfic, novels, whatever grabs you. See how others pace their stories, accent their characters, alternate their scenes.
I could see that you were working to overlap situations between Sam and Lana and Dean and Lupine, but the perspective and POV shifted so quickly and so often, it was hard to keep up.
One of my personal quirks is seeing the characters from Supernatural fall too quickly for a love interest. Attraction, sure. Desire, absolutely. A fling, a connection, all of that I can buy... but falling in love in two days? Love at first sight? I don't really see the hunters allowing themselves to be that vulnerable -- BUT, that's just me. Doesn't mean others would agree.
I think that your interest in these two shows can certainly fuel your desire to tell stories, and if you keep at it, you will continue to improve and draw readers. Writing is a passion, and it's my belief that it should never be stifled.
