pretty cool. Watch the video quality though, I watched in HD and it was still not very good quality (your first video mostly, but your second a bit as well). It's best to add things on particle illusion and then go to sony vegas, so that you can tweak the quality settings on sony vegas. But, if you're going to go from sony vegas to particle illusion, then be sure to go back to sony vegas to tweak the quality. I don't think that would be a good idea though, because it might cause a bigger file size, but whatever. Anyways, nice effects.
