Love how jazzy/swingy the battle theme is, really unique take! Very nice moment at 0:55, impressive rhythm. The whole vibe feels so distinct, throughout the tracks. I think it might be cool l to add additional background elements to the ending theme, as the pallete you have already fits the theme really well. Which is great and sounds like an aquatic theme from a nintendo game, with the swing elements adding to it. Great work on this!
