I agree with Anati there you should have captured the Knight on d5 and was waay aggressive and lost the queen.
You shoud have taken his pawn on d5 rather than letting him as he would move his pawn on c7 or e7 which would leave the game quite open.
You lost because you only focused on one side of the board you did not attack his right side. The bishop on g5 should have been pulled back and you should have moved the Knight on g5 early and "transitional mate" the king by the Bishoop on h7 which would make him move his Knight on g6 Then you would have some chance to beat him because that Knight was really the one who was defending the e4 and g4 square. The queen on g4 would increase the pressure and you still had black bishop which would mean mate in 3.
After good game against Rybka I disapointed myself and had a bad loss at the same oppening against my friend and chess com player iogyiogy...
