on second thought, maybe there is more i can extract from that.
161 hands
you folded 134 times (not all of them preflop, as we know)
won 23 hands
meaning you lost 4 hands at showdown.
we don't know how many hands you won at showdown, and how many just because people folded when you bet at some point in the hand, so let's guess here: i am going to go with half, although that is likely to be too few for the SD hands. 12 hands won at SD, 11 won before that. the ratio of hands you won at SD to hands you lost at SD is 12:4, or 75%. that number is way too high. it means that if you bet more often on the river, you will probably win a lot more.
121 folds pre-flop. assuming you would not limp (a.k.a. call) and then fold to a raise (a brave assumption, i know - but i am an optimist), let's see what else we can come up with.
you were first to act (or checked to) after the flop 56 times, counting all streets, 23 bets and 33 checks. not first to act facing a bet... this can only be an estimate... but you had 13 folds, and somewhere in the vicinity of 19 calls (some 25 calls are taken by pre-flop actions, but i guess you could have seen free flops sometimes from the BB). all in all, it seems you play too much with your own cards without a regard for the position you are in. again, you should be raising much more often, especially in late position - the dealer/button and the cut-off (position right before the dealer).
again going by the above assumption of 12 SD hands won and 4 lost, that would require at least 48 postflop actions by you (out of the total of 88 actions you took). obviously if you checked and then called a bet, this number would go up. actually, forget that, i don't think i can come up with meaningful explanations of those numbers without too much conjecture.
all in all - you are playing too passively. learn to bet and raise more aggressively, and you will be much more successful. also, play fewer hands. we know they look pretty, but there is no need to play any hand that you would not be willing to raise with.
