Some good quality, but needs improving.
Graphics for this were quite good. They didn't need to be incredibly amazing, and they weren't terrible either. However, the grass and sky was too plain. Maybe adding a little more shading and clouds would help.
Jay himself was very well drawn, however the feet didn't look very consistent. The head was definitely the best part. However, the red bits around his teeth made them look like they were floating.
The way in which you changed the angles was fluidy done, but could use a few more angles in between to make it that little bit smoother.
Loved the little tune playing through the flash. Added a great feel to it. However, the running sound effect did get annoying after a while.
I'd add a bit more animation, such as at the end, show Jay actually eating the dog. A bit of back story on why Jay likes to eat dogs would also help boost your score. People like story lines. So next time, maybe try something about a disturbed childhood.
Good luck in future.
