flash test pics

I just bought a new flash for my D200 a sb800. These picks are from today when I look at some birds for my wife. I want to say is how good this flash is. In these pics all I did was aimed it straight up and put the cap diffuser . at let the automatic TLL settings kick in. The only thing I did in photoshop was cropping. White balance was on zero.
The room was very dark . The only light was from the window and it was half blocked by a think burgundy curtain.

Surprisingly good, isn't it? I bought a D200 a few months ago and recently picked up an SB800. It's almost on the level of an F100 or F5 with SB28. Of course, this has wireless too! :D
