Since it's hard to attribute things like brushes when you're making digital art, I'm certainly not going to expect you to write a long list of all the brushes you used in every work. However, it would be good if you could link back to this page from your site/journal (especially from a "Resources" page) to let people know about these things.
And it would be nice if you would leave a comment.
