It is very well-composed, you can hear that, but I don't truly like the full package. As 'vibing cat' says, it is likely due to the instrument choices. I think, with a slightly different choice of instruments (I'd say, take inspiration from other entries, many use FL and different VST plugins!) you got yourself a banger right here! :D
That said, it is a nice entry for an Anime opening, good job!
