Nice Vid...
I checked out ur site too, gotta luv that music.....anywayz, the best piece of advice i can give for a slideshow like this is that you need to fill the background with something, perhaps a field of swastikas or a nice neutral colored background, or maybe one that changes color and stuff, also, it would be good to experiment more with how the pictures come in the flash, try learning about masks and stuff, but this was good, gut gemacht!
