Nice shots! I have had my Sony a6000 for a month, still learning all it's nuances. Overall, I think it is fantastic, best camera I have ever owned. One word of warning, some of my holiday shots were effected by sensor dust, I have had to fix hundreds of them on photoshop. I suppose I was not carefull enough when changing lenses. I got a sensor cleaning kit and did the job of cleaning the sensor myself.
Please take great care when changing lenses, and get a sensor cleaning kit. Eventually you will need it, or be ready to pay for a professional cleaning job. Cleaning your sensor yourself involves considerable risk of damage if you do it wrong!
