Alpha vs. Omega Sketch

Will move this to scraps later but am very interested in getting this critiqued or redlined.

This will be my submission to the 's contest. And because I'd really love to place (and at least get a free calender. :3) I'd like to get this perfect! Please note that the background is like it is because most of it will be too dark to see much of anything except for maybe highlights. I tend to go in and do all that sort of thing with paint rather than lines.

Anyway, critique the hell out of this, please!!!!! Watermarked 'cause I don't want people colouring it though. >.>;


EDIT: Made the following changes;

1. Lengthened the Alpha wolf's neck.
2. Shrunk the image a bit to allow the Alpha's foot to be seen.
3. Changed the reaction of the werewolves in the background, making them appear less "placid".
