I think it's realy danger for black. You should play Nf3 in secund move to prevent Qh5. Move like f5 create a dangerous weeknes in f7 squer. But I think there is many better defences against 1.e4 if you don't wont play 1 ... e5 try sicilian(c5), caro-can(c6) or scandinavian (d5). I recomend the first two very solid deffences.
Dangerous Defence?

White should have done 20.Qxf3 and followed through with Qxd5. Once the queens are exchanged it then is easy for white to win, having a large material advantage.
I've been looking at the Bird's Opening recently and decided to try it playing black...not knowing what to do this is what I did: any comments on improvements?
