A few comments from the beginning of the game.
Judicata is right about P3. After he pushes down against your stone, it is very weak--your only choices are to abandon it--the initial play becomes absurd, or make it heavy--easy to attack.
11: R5 is not wise. You have one weak group here, and you are playing to create another. Get in the habit of asking yourself "is this group weak?" You should certainly try to avoid ever having two weak groups close to each other. Your opponent will be able to build up strength attacking one, then use it to hurt the other group.
15: Instead of S4, I think I might extend up the right side perhaps to R9. That gives you a bit more room, and you can always play later at S4 if you absolutely need eyes.
23: It feels like you're trying to attack white here, but this can't work well. You can only attack where you have some strength. Your group on the right is ok, but not strong, while the group on the left can be attacked, and white will profit from doing so. Maybe play K3 to make yourself more secure. Note that white gives you a gift at
--he goes easy on your weak group. 33: The only move. Remember moves like these.
There are several places where you could play on the right to shore up that small black group in the lower left. I think I'd take R9 as the place to play.
as played is not good. Do not play the "armpit hit". It is only a good idea if you are trying to make life for a group and you have no other options-- and usually if you find yourself in that position you made a mistake earlier.
