Adorable moggy, she is very very cute!
Without DNA testing (and with dogs the results are dubious, with cats way more so as so so many cat breeds are not at all old and/or are very recent crossbreeds) you really can't tell anything else.
She looks to be semi-long hair or possibly even long hair depending on age.
Tabby is a dominant colour pattern to almost everything, and LH or SLH is very common, so neither factor make her likely to be any particular breed. Ears look huge because shes a kitten, they've almost all got proportionally large ears when they are little.
See how she grows, if shes a Norwegian or Siberan Forest Cat x or Maine Coon x then she'd be significantly larger than other breeds but even then, the size range in cats is vast, moggies can be anywhere from 2kg to 9kg+
Generally speaking first x or pedigree cats, even without papers are sold for a higher price and listed as a x so if your kitten wasn't sold as a specific x.. she isn't one.
