There is no reference pic, so nothing to compare it to. If you are looking for comments technique, I would say your fine line work is getting better. The dots at the tooth tips would indicate that you are holding the brush there to long while making the lines. I'm guessing slight hesitation between going up and then back down. That can be corrected by letting off on the paint when you reach the end of one side, then back on to go the other way. Practicing connecting dots with lines will help. That heavier spot on the neck spidered, which could be a lot of things.
Like Jackie said, 30 PSI is pretty high. I know I suggested it, but that was to fix a specific problem, getting the brush working. If you plan to keep working at that pressure, more trigger control as far as paint flow will have to happen. Otherwise, reduce the paint more and run at lower pressure.
It's a constant battle. The ebb and flow of paint vs. pressure. We all figure it out with time and practice. Keep painting and keep the questions coming.
