nice!
I'm not really into flourishing, but that was pretty nice. Unlike the other person, I didn't think it was sloppy at all. Sometimes, people just don't want to give another person credit if they're not well-known or if they're below a certain age group. I think it's pretty nice. I think that's a good length for a flourish too! If you do too many flourishes, spectators just get sidetracked and confused. Flourishes are more smile getters than reaction getters. This particular flourish would work well within a routine, which should be a magician's main focus anyways. The effect is always more important than card acrobatics. Blackout would be a good name.
