Fix lighting in video and remove seaweed

I need this video editing for my swimwear brand. I was sent it by my videographer but I feel like the lighting does not look normal, the colours look washed out and the models skin very pale. It is like there is a filter on it. I want it to be adjusted so the colours are more bright and vivid and the models skin is darker.

Also there is a large amount of seaweed on the left by the models feel which I want to be reduced if possible as it is quite distracting.

Here is a link to the video - https://www.dropbox.com/scl/fi/12gxkqwx42by8k70n0w3q/607A1756.mp4?rlkey=bjxpji6gvd5f1rvhclktejwvo&st=71u3si82&dl=0
