Congratulations.
I've done a few of those for friends, even if I didn't get paid.. but I'd definitely be more nervous if it was a paying client. The light is always an issue with these things as well.
I think this is a good step. The outside world needs your talent :)
When money is involved there is a huge extra pressure. You can't go "I wasn't inspired" or "the light was not good enough" you just gotta make it work :D
