Recommendations for Ecommerce and SEO optimization

Hello everyone, I'm new here in the group, so If I beak any of the rules fell free to tell me.

I almost started the Ecommerce website as a dropshipping model, otherwise I have been working as a Web Developer for 2 years, so I would be interested for your opinion about the content, colors, whether it is user friendly. Also I almost started with On-Page optimization...accepted both criticism and praise :D

If you can give me advice for this model of Ecommerce regarding SEO optimization. I would really appreciate it. :)
