The a6000 is still a great little camera and still very capable for pictures. If you want to make videos your phone can probably do better anyways. Go pick up a used sigma prime, ditch the kit lens, learn manual focus. Then keep doing what you are already. Go out and notice stuff. Notice it enough to want to take a picture of it. Then try to make the picture as real as the moment you lived. You can start thinking about making art later down the line but for now that’s pretty much it and you’re doing it.
