Well... It was a good attempt. The animation is fairly solid. Though there's moments where the characters stop moving, which sorta takes away from the fight. I assume this was supposed to be like the Decisive Battle sprite fights as it seemed like the same style, but this falls seriously short. The battle is definitely needing to be longer since it was really short, and honestly, you should have just left out the last part after the fight. That meme is dead. Another thing is the sudden changes in music. I assume the first part was a nod to the Decisive Battle flashes, but then it goes into the Iris battle music, which feels like a complete tone-shift.
The animation is good. With a little practice and a little work, I think you could make a pretty good animation. It's just a matter of putting in the time and effort to do so. It feels like you gave up halfway through this and just stopped caring. If you put your full effort into another animation, I think you could do a pretty good job.
