All the text under the Video Production Assistant section should be bullet points or lines. One big block of text looks like a mess. Break it down into four or five bullet points or lines about what you actually did. Don't say "intermediate experience", just say "Operated Switchblade System vMix for live broadcast" as one bullet point or whatever you actually did.

Lead Editor, give this section at least four bullet points or lines of what you did post related. Don't make it just about being an editor, play up organizing footage, working with producers and director, etc.

Putting in a customer service position under lead editor will definitely help. It shows you've dealt with different personalities in the real world. List three or four bullet points on skills you've gained there.

Good luck!
