 Generally speaking, I wanted the photos to be the main defining experience that a visitor has. To that end, product
 photos became significantly larger in an effort to fill in the missing colors of the simple color palette I used.

 description and attributes allows customers to more quickly see the enticing and larger product photos together.

 I think the second best improvement is the individual product page where the photo takes precedence and shows off the
 quality of the product. A larger call-to-action makes it easier to add the item to carts and wishlists. I reorganized
 the product information as well to better prioritize it, visually.
