I'm just gonna check out your myspace for now, and I'm listening and I'm not a big fan of this genre of music so I can't really provide too much constructive feedback. However, I will say that the recordings sound very good - very crisp and clear - and everything is mixed really well.

From listening to these tracks it's very clear that all the people involved are competent musicians, but personally I am not a fan of this genre of music so the songs don't really click with me, but overall it sounds very good.

In terms of improving I think you could aim to write songs that people who like this style of music and people who don't will really like it. I realize that is a daunting task, but aim for it - you might not succeed, but it's always nice to have another goal. Overall, very good musicianship and great mixing.
