i am not a french defence expert myself because i play the caro-kan and the scandinavian defence but .......
1.i would suggest you to play3...Bb4 which is more annoying
2.many people sayed that 5 Bd7 was bad but it was actually the best the second best was nc6
3.after 8 Qa5which is a good move9Nc3your best move was Nc6 which gives you chances but you are still worse...although you played Ne4 which is a terrible move ...sorry
after f6 the game was over
have a nice day
there are a few interesting coments here but , a lot of chess snobery also ......
