Seed fundraise investor deck for agritech BI startup

I'm fundraising ~$500k in Convertible Bonds and head into investor meetings and presentations in less than 1 week. I have the basics - including the deck I used for my last seed round ($250k), the presentation outline, and key talking points - but I need help with getting an objective eye, getting this streamlined, and making it more slick to show off what my company has accomplished so far.
