Absolutely Awesome!
You have done it again, man! You used all of the (major) characters from the previous episodes (except the Sherrif) and added something new to them. My favorite change is with the Protagonist. I really like all of the bandages and especially the sunglasses he wears. They make him that much cooler, if it is even possible. If you feel satisfied with what you have done with this series, then I think it would fine if you ended it here. If you plan to make more all the better for society.
