The main problem with this question is, that there are no vision or goals defined. You think, the UX only about the UI components and their order on the screen.
The most simple answer to your question is: "A good landing page converts". ... converting can mean: sells, gather leads, gather subscribers, etc.
A very good starting point to understand why is the vision or goal is the most important thing when designing a landing page and not the components itself, is the Measurement Plan by Google. You can read about it here: https://www.google-analytics.ie/blog/google-analytics-measurement-planning-guide/
So, your focus should be on the goal, what you want to achieve with your landing page. Have more bookings for video calls? Build brand awareness?
About the wireframe: it has two, way different target-audiences. Business and career advices...and no info on the page that how differently you can help them. There is also no promise above the fold. Maybe below. The second component on the screen is where your experts worked at...it is not important. The most important thing, that WHAT WILL I GET / WHO I MAY BECOME / WHAT I CAN ACHIEVE when booking a mentor from you. The most important thing to know about the potential users is that they always want to be better selves. First, they need a promise and then a validation of your expertises that you are really classified.
Collect job stories and user stories and answer for those questions to provide value for your potential customers. Currently, 99% of your landing page design is about how expert you are, and there is a very little info about how good someone could become with your help.
