Good first try
I like these kind of shorts. I like your music choice and sound effects. However, you need to zoom in! Let us focus on one, maybe two guys at once. I would be watching blue head and it would go into slow-mo, so I'm like, "Stuff's going down!"
Then I catch red head finishing a cool move out of the corner of my eye and think, "Oh, dang it."
You have a solid first draft here.
Also, the characters look more acrobatic if they are better-proportioned. Make their knees bend when they jump and run to better emphasize their strength. You can see the knees bend better i their legs are longer!
