Is this template ready to be posted?
With respect this is not even close to the standards for here.
It breaks just about every fundamental design rule with issues with typography, spacing, margins, hierarchy etc.
There’s nothing unique or premium here that could not very easily be found for free online.
Take a look at successful items already for sale – their attention to detail, versatility, premium construction etc. e.g. Canvas | The Multi-Purpose HTML5 Template Preview - ThemeForest
I think it’s good you should do it
