Challenges of creating a new website

I recently added the link to my new website under my bio info. The new site is www.tatiana-iliina-paintings.com. My former (and still existing) site did not seem to have the potential to handle ecommerce the way I wanted. Since FAA isn't really set up for selling originals, the artist website wouldn't have done the job either. I looked at several platforms and finally decided to go with Wix. I forget the exact type but one of the more premium ecommerce levels. Wix seemed to be the only one that allowed me to make custom selling pages, instead of showing all the little tiny product images that the typical ecommerce sites allow. To be honest though, I am not too sure how this is going to work for SEO. Am hoping to be able to drive that with some elbow grease! Anyway, for now I feel like it is a good start. It's been a lot of work and hopefully now that I'm nearing the end will soon be able to get back to adding images here at FAA!
