I think they are cute too, and with a bit of refining, this could work.
Please be careful selling anything "Disney-themed" even if it's just the word 'Disney' that is used sparingly in your descriptions. Don't use Disney fabrics. There is a saying amongst those of us who make and sell handmade products: "the mouse will go after your house".
It isn't just Disney, either, so look into this further; read up about copyright/ trademark infringements. There's a whole host of things we can't do and it is a bit of a minefield. That said don't let this put you off, OP. We learn as we go along.
Anything sold for children - make sure you are compliant. I can't advise with this as I don't sell items for children, but I do know there are rules and regulations for this which are rather stringent.
If you sell outside of the UK, it's another minefield again with various regulations not just with the child safety laws, but postage, packing, customs etc. If you aren't selling abroad or intending to, ignore this paragraph!
Your photos need a bit of work, have a look at best sellers in your niche on sites like Etsy and get a feel for how they are marketing similar items.
Good luck and keep going. It's a learning curve, and it can be a lot of work, but I do think your products are cute, you just need to refine things a bit more. If this is something you're passionate about, keep going! x
