How can I improve my upcoming online store's design?

Hello guys, my store will open in a matter of days, but im sure it can be improved, im looking for suggestions & ideas about the design and any other areas.

Specific areas im looking for suggestions: (Those areas i think are poorly design, so i must change them for sure, but im looking for opinions on the website overall.)

  • The header and color of header
  • Website style (colors)

Thank you.

Website link: It is in my signature
