From the videos I've seen, you have a great voice for commentating and talk at a pretty good pace which is pretty great. The intro is pretty nice, too.
Getting well known on YT is really hard, but I will give you a tip. Try to be active in a forum where you promote your videos, and instead of just making a thread with a link, put the link in your signature instead (with something that'll interest people). That way, more people will feel inclined to check out your page, rather than regard your post as spam.
