E-commerce Dashboard UI

I created a design for a e-commerce dashboard ui. This is to be used for online stores. This design displays the "customers" tab where information about customers is displayed.

Original concept statement:
My idea is to create a dashboard to be used in the management of an online store. The audience for this dashboard is individuals who are managing an online store. These individuals could be any age, any gender, and located anywhere in the world. I want the UI to be simple and neutral, something that is seamless and non-distracting. This concept comes from my experience with the Big Cartel online store management dashboard.

HTML + CSS coded version (with mobile):
