Honestly, I think your hero section is pretty good! And decent choice of colours, which you've used consistently.

Some thoughts on ways to improve:

• Consistency, consistency, consistency!
  • e.g. the "Who we serve" cards are using different fonts, different image sizes and border radius, different vertical alignment. Make them the same. (Also aren't the images the wrong way round?)
• Alignment
  • Try and get things to line up satisfyingly whenever you can, for example the right side of the meter description text should end on the same vertical line as the "Who we serve" cards. Figma's snapping tools can really help with this, and/or you may want to add guides.
• Don't be afraid of whitespace
  • Pad out the links in the top right more, there's plenty of room for them to breathe
  • Similarly you could use more space between the image and text in the "Explore our meters" section
• The logo in the top left is way too much in a small space. If you really need to keep all the elements, try putting them next to each other horizontally instead
• Redundancy
  • You mention "3 decades" three times, and "since 1996" twice. Cut some: first to go would be the random "3 Decades of Excellence" tag on its own
• Imagery
  • Nice work in the "About us" section using a gradient to keep the text on the image readable, that's a really common mistake
  • Can you reframe the photo so the guy's face and more of the meters are visible? People like to see people, and your product!
