Just before commenting I'd like to say I'm not an expert in the French.
3... c5 looks weird to me. I'm more familiar with Bb4(Winawer) or Nf6 (Classical).
Your real mistake was 6... Bd7. Your opponent could have won a few pawns with 7. dxe6! (I'll let you sort out the variations. PM me if you need help.)
11... o-o-o was daring :) I'm not too sure if it's safe for him to take the f7 pawn but it seems alright to me.
14. ... Bc5 is a mistake (or rather you have a better move) 14... Rg6! wins the Queen.
Those are about the few things I can see that you missed. You annotated the rest. Good game and good luck.

Hi,
this is the first game I post in this forum.
I played this game earlier today and would like to hear your comments on the way I played and whether there was a winning combination that I overlooked. I have annotated it myself as well as I could.
I played Black, using the French defense:
I'm grateful for all help I can get analyzing this.
