I made a move at C7 to attack the white group at C5. It failed. I'm interested to know what the better move there would have been. Also general comments on the game will be really helpful.

Thank you.

Game summary: 

Both players sometimes choose the wrong direction. White was too passive in this handicap game and often played too small. Black should not save every single stone and look more for sente moves
