So, here is my feedback for you:
- If any aircraft asks a RWY change, do not clear it directly, give the aircraft a enter pattern instruction with sequencing if necessary.
- Contact aircrafts once they’re 25nm away from your airport.
- Use the “exit runway” command at around 70-80 knots. I didn’t receive anything.
- If possible, respond quicker.
- The airport wasn’t really busy, so I couldn’t check this point but, in the future, use sequencing. It will help you a lot.
I’m sure a scouter will help you to get better and better, just ask nicely and I’m sure someone will help. I’m looking forward to see you controlling the skies of the Expert server 
Thanks.
