Shots look good, especially when you consider the difficulty. ISO1600 to 3200 seem to be required, so you've done well to produce some seemingly low noise images. I like the last one due to the abstract nature and lighting. I don't think flare is a negative in this context since that's part of the production. The INSPIRE tattoo is a nice addition. A 5D II is really a handy tool if you think you can get ahold of one. I've been shooting a lot with that and the 70-200 f/2.8 and still am able to get some shots when you happen to catch a motionless moment.
