I'd suggest to add an about page [it will be mandatory as of Jan]. Add policies about returns, exchanges and cancellations, I think that's important for a lot of buyers.
Since you are selling baked goods, I would also let buyers know that you are working from a commercial kitchen. [assuming you are, if not you may want to check your states laws & regulations about selling baked goods]
Also, be weary about using big name characters as Disney does sweeps, you could get fined or get your shop closed down.
I hope this is helpful and not overwhelming :)
I'd also suggest to go through the seller handbook. There's some great sections for beginning your shop.
