You might want to loosen up. Open raise more hands.
But dont start raising 10% more hands over night.. just slowly start adding hands with good playability to your openraising ranges.
You are playing very tight which can be good for begginner but you need to loosen up for sure, but as i said this procces should be slow, push your comfort zone a bit but dont overdo it.
I recommend watching some videos so that you can see what hands coaches openraise with from different positions.
Also isolate raise bad players who are limping a lot, they tend to fold to cbets a lot.
You also play very fit or fold postflop. That doesnt have to be a disaster at micros but you are most likely folding best hand too often. Once again tho, dont start calling down every midpair just because ppl on the forum said you are nit.
Watch some videos, try posting some hands which you are not sure about.
You will see you will find out you have some serious leaks and some of them can be fixed in just 5 minutes.
Keep it up
