Hard rejected my template.pls suggest or give advice
Sorry but with all due respect you are a way off yet.
Currently it is far too simple to compete here. Right now it lacks premium feel or features.
It needs a more modern and refined design, more features, pages/elements and uniqueness (right now there are tons of sites on here which offer this type of functionality and features).
Beyond that the fundamentals like typography, spacing and alignment all need work.
Noted your feedback…
too simple, you should add unique details in its design
Can you suggest some sample links to be consider for more features in landing pge html?
