Please give me a feedback about the HTML template I have designed.

I am currently designing a Rent Car website template and planing to sell it on themeforest.

Please provide me a feedback about the website what kind of change is required?
(This website is still under construction)

There are visible improvements needed in this template, first of all there are spacing problems in the theme, secondly, you will have to improve the design as well because the font selection and design idea need more clarification and new sections.

Thanks for the feedback and I highly appreciate your answer.
