User interface feedback for minimalist product review page [closed]

I'm a novice currently learning user interface design in my free time.

I am currently designing a minimalist product review page for the mobile phone. I would like to get feedback or suggestions on how I can improve it?

I would like feedback on the below following points explicitly:

  1. Where should be the title of the product? Currently the title doesn't seem to in a right place in my opinion.

  2. What can be filled up in middle empty whitespace if the user did not leave any comment?

  3. Is the blurred gaussian background a good idea for the product image?
