What drives you to do art?

To be honest, I've been wondering about that myself. At first it was because I enjoyed it, not that I don't now, but being in college and thinking about careers and stuff has made me do some thinking. Of course drawing porn hasn't helped at all, even if it is fun and sorta liberating in a sense.

But I still like what I do regardless and I often find art to be stress relieving, when I don't have other things going on that is.

Excellent. Art for the sake of art (and indeed it can relieve some stress too and take the mind to other places). Porn is ok...but it's not an end to itself. I find most of it rather boring and would like to see imagination more than porn.

Keep up your work on art and your practice. You can only get better as the years roll on and then you'll have something neat to look back upon. :)
