If your goal is just to have fun, and make clothes that you and your friends like, then keep doing what you're doing. Don't give way to hate and just have a good time.
If you have serious intentions on entering the street wear market, you need to consider a few things:
What new ideas or products are you offering that isn't already available?
What will happen to the brand when you split up and go to college?
Do you have time to commit to making enough stock?
How do you plan on advertising and getting your name out?
