Do you plan to go to college or art school in the fall? I have an art degree from college but have never really used it. You do have a real talent and I think you should be able to use it and get something for it. Maybe you could start here on pettalk, you may find a connection to a publisher if enough people see your drawings and like them.

One thing I have never gotten to do is see U2 live in concert and its something I've wanted to do for about 20 years now! My husband and I are both fans, we have seen their Elevation tour special on MTV or VH1 and we have it on tape, I love that heart shaped stage. You must have loved seeing them live - 3 times!(I am so jealous!)
