Feedback on picture

Noone has mentioned that model releases are needed for at least 2 persons when the photo is lightened. 

There are at least three water drops on the lens that must be removed.

The portions that are cut off on the left and right sides need to be removed. I.e. the arm on the right.

Here is a quick example of what can be done:

Not enough light which causes noise.

If it would not have unfixable technical issues, you would need a model release from every recognizable person in the picture.

Very bad light. It's extremely difficult to shoot photos in these conditions.
