What whirly said, with knobs on!
As an FI I'd far rather fly with a pilot who is
aware of what they might be missing or struggling with - far more worrying is the stude who makes a howling error without even being aware of it.
Well done for noting, even afterwards, the things that you would like to have or should have done better on - this awareness will help you to get to where you want to be in terms of capacity. The big thing IMHO is to ensure that you keep setting yourself higher and higher standards and work really hard to attain them - aim high!
