Looks like you've got some great things to start with. I think morgandawn posted resources on vidding awhile ago, she was helping with shows etc., you could look at tags on her old entries or contact her if you have questions about vid conventions or standards so yours will work in with other vids etc. (MediaWest and others.) I understand feedback at these events is really helpful, but I'm not into it enough myself to be able to give direct advice.
