Here's quite a good website for modern day subcultures: Yourscenesucks. The website isn't a serious thing  but largely mocks the idea of subcultures or "scenes" saying that they have lost any deaper meaning or philosophy behind them (non conformity, rebellion, self expression etc.) and are now just corporate supported commercial fashions that everyone follows in one way or another and get rid of any sense of personal identity. This is quite a good thought to keep in mind when looking at this subject: all the looks and youth cultures quickly become meaningless, commercialised, commodities.
 The website also has a list and description of a range of modern youth cultures. Each is mockingly described and comes with a drawing which is useful, it actually goes into quite a bit of detail, in a satirical sort of way. I'm going to have a more in depth look at the site as I think it may talk about earlier influences to these cultures, such as punk and glam. This would add some wider perspective to my work as it would help show what became of the cultures I am working with.

I may do something similar to this.The artist is page creator Rob Dobi.
