1. The header
Make it so that the header's background blends with your navigation menu, there is a little line which breaks the gradient colors.
2. The hero section
Bring your image to the middle of this section, it does not make sense for why it's way lower than its intended place.
3. The featured tools
Make it either boxed or if you want it to be full width remove the borders and shadows. plus add at least 10-20 px top margins.
4. Pricing plans
Add the prices in a boxed layout, Add a border to your prices too.
5. Define the section below the prices, what can it do for the visitors? is it something that can be brought? is it a monthly free tool?
6. Explore page
It feels too white, add more colors or make it more orderly. There is no back button. There is no other menus like login and so on.
7. Product page for ex: LogZab
It feels kinda white too something with no soul. The sideline borders seem invisible.
I'll take a more throughout look today and add other findings too.
