PITCH 1

A band is definitely needed, in order to include instruments obviously heard in the track, such as the electric guitar and drums, and so that within a performance the artist is not singing alone.
The setting of the garage is good as a performance venue.
The suggested artists, especially Becky, were good, in terms of distance, look and experience.
The use of animal masks and the setting of a field would not contribute to the music video and so should be avoided.
White water suggests rafting and turbulence. This should be considered when filming the cuts of the water.
An idea of filming a water cut is water droplets running down a window, maybe with the subject looking out of the window.
"I keep drowning in white water" is the line repeated multiple times in the song.
A slow mo of a stream of water could be inserted after the first chorus.

FEEDBACK:

Find the lyrics, analyse to find what they are about, and what mood and feelings they convey.
A full performance will need to be filmed prior to editing, so where the cuts need to be placed can be decided after.
A second pitch will need to be made, including more information as to the artist and band members for example, to avoid being too vague.
Contact needs to be made with the artist to confirm the use of song.
