Photography camera question

y

Hi ladies , I know this doesn't have anything to do with pregnancy but I wasn't sure where else to go

Anyways I'm in need of a new camera. I love photography but I do it as a hobby. I'm currently using a Sony NEX 5T but looking into something "fancier" I guess. It takes great pictures but I'd like to go more professional with it.

Do you ladies have any suggestions ??
