Artistic enough?

I have never thought of myself as artistic, just admiring of artisans. I have never taken a formal art course, but now I would like to.

I have an opportunity to try and teach stamping at the local art supply store/gallery. I have been asked to bring in some samples. This is worse than a job interview. It is not just my character that is being evaluated, but my ability as a stamper. Here are some cards I have been working on to take in.
