Went to showdown 30% is what seems to be the biggest problem, or at least the biggest leak I can spot right away, went to showdown is at about 25% at a winning player at 10nl. also, playing 24/16 is not that good, vpip and pfr should be tighter together, somewhere around 23/19 or 19/16. this tells
me you call way too much with marginal hands, like JT K9s A6 etc you should give up on these hands because most of the time you hit a pair you have no idea if you are good or not, and I assume, like if you hit an A with the A6 hand you will call down to a showdown, and I believe this is how you lose a lot of you money.
I bet there will be some people who can spot more leaks. but the went to showdown, well, think about folding more to river bets. your fold to river raise is 49%, regardless of who you villain is, fish or freaking phil ivey, you simply have to fold a lot more to a river raise, unless he is insane he will not bluff with a raise on the river so you should start folding those top pair type of hands, even 2 pairs if the board is scary with flush draws and straight draws.
