I like the one around 0:34 because you sound more relaxed and natural. I'd like that one to be closer to, if not in the very front, because everything else is... Okaayyyy, but to put it in a strange way, it's pretty "animation" and not "raw" and believable in a personable front. At least, not yet. It's getting there, but alas, while acting is acting is acting, commercials and animation require different approaches. Most of it sounds like I'm "being sold to", even when you're not trying to pull off a hard sell approach, so you'll have to check out Nancy Wolfson tips/videos (some on YouTube) and do some heavy duty practicing to internalize what you're learning--Trust me, I KNOW how hard it is to learn how to do commercials after doing sooooooooo many big personalities!
