i see you play many games already..i believe opening wise..you're comparable to most people. I suggest to improve your game, you should play a few 'feng zi' or mad games..all out attack..dont worry about the result.
for example, your game w qingfeng....57 pao play until feixiang...v. wasted. the logic of center pao is to whack...n midgame..u change your mind to a defending one..not good..unless you're really sure about what you're doing.
therefore..relax..enjoy the game.enjoy outwitting your opponent....try hard...die fighting down!
