piano sketch 2 minutes work in progress feedback request

Hello every one hope you are doing well.
i am working on a composition which are inspired i supposed cinematic soundtracks, late romantism and anime.

How well do i have control over the drama?
Does the piece collapse under it self at some point? (cohesiveness)

What about phrasing or melody? is it clear? 

Personal critique:
it seems to change drama in the second half of the piece which may or may not be for the better.

The tempo may be too fast?

The climax is very sudden(second half of the piece)
There may need a better transition.

If the mood changes in the second half it should at least have the same drama.

Anyway.

Looking forward for your critique and comments ! 🙂

Thanks in advance.
