Why don't I ever finish things?

I have wondered for a while now, I always start drawing on big things I wanna finish, which I am actually quite happy with, and when I have finished either the sketch or the outline I get too lazy to do something more. Ffffh, it's annoying!
Anyway, I'm working on this thing here. Though I wont ever finish it. 

 I had planned to add blood effects and such when I finished it, as Ai is in her demon state. She's a sadistic bastard in other words. <3

Nothing is going on that is worthy updating you guys on. I have finished D.Gray-man the anime, which I HATED the ending of. Seriously, Aniplex, try to at least follow the manga more before you quit in the middle of the damn plot! D:
What about Kanda's past, or more details on Allen and Mana? And what about the Noah's, which you get to know SO much more about in the manga! ; n ;
I'm in despair! Aniplex and their crappy following of manga has left me in despairrr! ; A ;
