I really like a lot of your pieces. They're so warm and inviting on their own, though, that I feel like the wood background in your photos is kind of sucking the life out of them. (If that makes any sense...) Their unique glazing hardly stands a chance against the grain of the wood or the shrubbery in the background.
As a mother of two dogs and no real children, my eyes immediatly went to your dog bowls, which are only a portion of your shop, but just a few thoughts on those...
Your dog bowls are awesome, but only one size. I'll give you my scenario, which other buyers may have as well: I have two dogs, and they have appropriatly size bowls - a 1 cup bowl for the Pomchi, and a 3 cup bowl for the Golden Retriever. The bowls match each other. I couldn't buy them matching bowls from your shop, though, because you only offer one size. So, I wouldn't buy a bowl at all, because I want their bowls to match.
You also don't mention how many characters the dog name can be. I looked at the names on your examples, and thought maybe only one of my dog's would fit. Try giving the customer more information - not just on the dog bowl but on everything else as well.
On your tumblers and bowls, I suggest listing individual pieces. As a shopper I like to know exactly what I'm getting. Your listings for these items are vauge. There's no way to tell what exactly you'll be getting. A lot of buyers will just move on to a shop that shows them the exact item.
