Drawing a 4 steps instruction diagram for online Ecommerce website

Hi, I need to make an instruction illustration to attach to the E-commerce website's description.

I have attached similar instructions here, basically copy exactly the same, but I want to have a better design, on color palette, theme, etc.

For more information, we can discuss it in DM

Please also type "ABC" when you DM, so I know you are a real person.

Thanks!!
