Hey serbian.. it looks like you spot where you went wrong and thoroughly point it in your annotations.
You certainly have an advantage out of the opening.. maybe after 12 Kd8 a solid 0-0 was better ? The idea being.. allow him to protect that isolani and give him a second of breathing room, it doesn't matter because it will be a target for you the rest of the game and should inevitably fall and overall the idea behind the attack, instead of an instantaneous crushing blow it is a positional squeeze on the victim like a python.
Also I think (from my own experience) when I get a pretty big attack that looks promising then the tendency is to search and search and try and force the position to keep the pressure, when I think having reached the advantage a lot of times solid, even quiet moves can be quite devestating to setup further prepartion for converting the attack.
BTW comment on my thread dude 
I dunno I did something in that thread to turn people off i think I cant get any responses!
*Edit* BTW in my game it is the same Idea, i ended up with a pretty big advantage/attack only to blow it because of obsession with keeping the pressure/initiative
In this game I played a guy a couple years younger then me, I did good in the opening and put pressure on him and he was clearly very underdeveloped, i knew i was winning but i didnt know how to finish the icing on the cake!
What could i have done better in this game?
