i admire your work, you were the same person who made Rojay the legend of the Dragons which i think is great, i have read your authors reports and i know the challenges that you face. So i strongly believe that you are amazing and on top of that many of the people here have drwing tablets, lessons, a working cast, studio for animation and other enhancements. For you to do this in that time frame with a simple optical mouse you are a genus.
As for the animation it can have improvements, the audio needs work but the story is great, the explanation was not necessary because Hulk can never ever hurt superman. I am no fan of either toon but facts is facts i have seen Storm from x-men kill the hulk, i have seen the comics & in three edition superman pulverize hulk and left his face stuffed with rubble for break fast and in one of them the hulk was beaten so bad by superman to the point where he was knocked unconscious and superman did not have a scratch.
The colours were good, the coordination of gimmicks was good i enjoyed it.. it made me laugh especially when hulk pick up some punches in his green ugly face hahaha haha and when he landed on his face as banner the sound was funny splak! like a dumb rag doll hahaha i am going to give you an offer where i will show case your work on my channel. we will talk keep up the good work.
