Chris has made a good point about being careful about what you share and how you share it. I don't know who your teacher is, or their ethnicity. You might want to recall that if they are ethnically Japanese, or really steeped in the culture -- they may not like to say no. Make sure you understand their answer and opinion. I don't teach within the Bujinkan or any other form of Japanese art, but you might notice I rarely go into details about my style. We've been advised that we should use a great deal of care in what we post about our art -- so I do so.
