I have been on YouTube a while though am only just starting to put a little more effort into my channel. You can find it here http://www.youtube.com/amylovebrierly
I've found the YouTube Creator Academy to be very helpful, also watch other YouTubers to assess the way they film and edit things. I always love watching bloopers! Everyone makes mistakes, so make you video... post it and accept any feedback you get from them to help improve your channel. As my channel is still building up I do not get many comments but learn by reading the comments from viewers on other peoples channels.
I think just by recording, posting and learning more about editing as you go will help you in finding your on YouTube style. A learn as you go kind of approach. Asking for help is a great start!
I'd check out your channel but am at work right now and can't access it. Send me a message and I'll check it out once I get home
Happy to help you and share.
