Thanks!

With respect this is not up to the standards for here.

You need to tighten design basics esp. typography (font choices, hierarchy), padding, alignment and spacing (portfolio items dispersal, about page spacing)

You need to add significantly more features and functionality. I get it’s a minimal design but these are overdone in the marketplace and would need to be flawless in design and execution

Hello, your theme is not market quality, there are many errors, there is no unique side that shows your design as a premium.
As a recommendation I can tell you this
I think you should learn design principles
And if you learn design principles and ui / ux design as a road map that can advance you and examine the products in the market a little, you can understand that quality and advance yourself
Be faithful, you will surely succeed when your patience as a recommendation to you is a little warm.
And we all went through these roads and I understand your anxiety and excitement
Follow an accurate road map and take some time
Do not give up, your success depends on your trust
Feel free to discuss
I wish you success in your step
Thank you very much.
