Nice work
Have to say you did a pretty good job here. Reminds me of the older 70-80 cartoons where you had two characters chasing each other to outwit and gain something from each other. Like how this one ended differently with the bird being eaten by both foxes and as a bonus they got to eat all the fish as well. One female and a male fox, cool.
The animation was very nicely done here, you did a superb job with the storyline as well where both foxes simply want a fish but can not eat any because of the stupid bird aggravating and giving them a hard time over getting any. In the end they used dynamite and got fish at last along wit hthe bird as a tasty meal.
The audio used was quite nice here. Minimal voice sounds made it good. Just shows that not every movie needs voices in it to be good I think.
Overall, brilliant.
