First post updated; several roles have been completed. Congratulations to da1edw1n and Mongoose for fueling the juggernaught on its inexorable and crushing journey towards total voice acting success.
I'm thinking of contacting a woman to play Captain Kristae. Lumin Kristae sounds fairly feminine, for whatever reason, and female VAs tend to be better than men in the amateur circuit. I'll poke around on voiceactingclub and whatnot.
Well, bahijal, I'd suggest slowing down a bit (something you can definitely control) and getting a better mic (something you really can't at the moment.) What do you use to record your samples?
