Looks okay.
You have room to open up your game though both preflop and postflop given your PFR is a bit on the low side and W$WSF has some definite room for improvement (aggression seems to be on the low side). However, I think you are very likely +EV at 50nl despite this and wouldn't discourage you from moving up until you have a reason to drop down.
What is your fold to flop cbet?
