Getting close
I couldn't understand the end dialogue, so with that in mind here is what I think:
The fight felt like you were holding back, for whatever reason. It felt very tame, when what I think what you were going for was epic.
What I would suggest is that you storyboard your fight scenes first.
When you are storyboarding, you are a lot more 'optimistic' about what is achievable - then when you start to animate you actually aim higher than what you would normally think you are capable of.
Keep at it.
