I had to go but here’s feedback
A little tip is to control at small airports and regions that are not that packed
I waited like 6 minutes for my taxi clearance and at that time you were not having that much traffic.
I asked for a runway change and you told me to go around, when I Request a runway change you should send me a pattern instruction, sequence ( if there’s more traffic to land in that runway) and then clear or if you don’t want me to go to that runway say “Unable”
You were also clearing people for take off when landing traffic was 1NM out it is more safer when the first plane to land is at least 4NM out
