Can someone suggest some mixing sites or aid?

My project has just learned exactly how critical the mix is to recording, and I wanted to get as much information as possible. Auctually, any info with protools LE and mixing in protools will help alot.

For an example of our stuff here is our myspace pagewith a link to one of our songs... it is the most presentable mix of the bunch IMO. www.myspace.com/thechaostheorm

If anyone has any advice, info, critiques, or comments, please share! Thanks!
