I think I am getting tired of working on this one too and want to move on to more. That might be the deciding factor to deciding if it done or not!
So since I started I have found a few other people who do this style of painting too and have been devouring their blogs, You Tube videos and Flickr pages for ideas and techniques. The people I have found so far are Flora Bowley, Tracy Verdugo, Connie Hozvicka, Michelle Fauss, and Justine Aldersey-Williams. I would love to know of more, so if you know of anyone else doing this kind of "intuitive" or "fearless" painting, please let me know in the comments! Thanks!
