Being that I am a big fan of Wile E. Coyote, and his alternate Ralph Wolf, I decided to give this a look. Overall it was alright, not spectatular, although i believe if you had given it more time and smoothed out the animation, added some better sound effects(such as the dynamite explosion, it sounded far to weak) that it had the potential to be an excellent peice of animation.

I did enjoy it, but I have to say, given the nature of the characters, Wile E. Coyote amputating his arm at the end seemed a little over the top, but being that it is a parody, I'm not really holding it against you, I just feel it would have been better to stick to the classic nature, since it seemed like through most of it, that was what you were aiming for.

I wish you luck in your future projects.
