Hi Priscilla,
Your artwork is lovely (in fact, I favorited a few items)! I noticed your shop sections are set up by size, but I'm thinking shoppers might like more specific descriptive shop sections like "sea life," "birds," "animals," etc. (I know these are pretty generic terms, so you might want to fancy them up a bit, but you get the idea.) That would make it easier to find what they're looking for.
Good luck!
