Could have a little more
I think it's a little short to be a boss battle, but it's a good start for a track. I think that you've got a good foundation that could be built upon by adding additional extras to it, like a solo and then eking the track out for another minute or two at the very least.
If we're talking video game combat here, we need to assume that there will be more than 55 seconds of the fight, so it needs to be a little more than we've got at present.
