How many stars do you give if you review it?
With respect this is nowhere near the standard for here. It’s not productive to give it a star rating as it is.
You need to spend time refining your knowledge of design basics and look at the popular existing items to understand the level of versatility and attention to detail that they bring
how make more creative
You need to address design basics first - without those then any big (creative or not) will be futile
now what is basics
You need a better grasp of the best practice principals behind typography, construction, hierarchy, spacing, other general UX, etc
Right now it’s a selection of poorly executed, generic UI and elements chucked together on a page with no real structure
This is even more important if you are submitting design items rather than coded templates
Again with respect this is a premium marketplace so things like this should be a given
