I agree with Phantom that the navigation buttons could be improved. I'd like them to be a bit taller so they're easier to hit.

I'm probably not in your target market. (My Presbyterian upbringing makes me sensitive to evangelism. I tune-out...) But I'm a huge fan of Maxfield Parrish and Alphonse Mucha and have bought art prints and books of their works. I could almost see myself buying your work. I think your pages about technique and composition are simply outstanding. Really, really, outstanding. I also like the Emeerald Isle reference to Ireland and Celtic heritage. (I'd like to have found more about that in your text. Instead I found myself reading about the sin of pre-marital sex.) You could probably sell art to people like me if you'd focus more on the art itself. Otherwise, you're only preaching to the converted.
