Good job! Homework #1 Done!
Witt that sample of the stats it's not much to do.
It could change a lot with couple more K hands either to better side or worse. But overall right now they seems to be good. Only the W$SD is really bad which may tell that you going to much to showdown and not winning at all.
Most of the weakness you wrote can easily be fixed by posting hands (analyzing your session). We will start writing feedback to your play. Usually negative feedback will put you into thinking phase and trying to fix all those leaks. It's almost the same as you lose money, you will remember it more than winning part. By this situation it's gonna be that negative feedback you gonna remember and try to avoid them next time.
What about tilt? Do you adjust something against it? For example:
Easiest way to fight against tilt is to set up stop-loss technique. Which means if you for example have lost more than 3BIs for a session then you just stop the session for some time. The BI amount is set up from your own results. Some may put it higher, some lower. Also after the stop you can spend some time with evaluation part to become better.
Tight style is usually called playing selected hands. Like following the Starting Hand Chart. Aggressive should be also pretty clear that already the word says how you should be playing. But the problem playing aggressively is that you have to watch that you don't play too aggressive. Find good spots, find good targets. About The tight-aggressive strategy you can read in this article: "What is the Big Stack Strategy?"
