Ed you have something so many artists like me would love to have a totally unique personal signature style and vison. No one can teach you to have this, and in your case it is so special you cannot follow a path that would make you a "Russian Realist" you have to blaze your own trail, which is a joy to follow. Yes its harder than following a more traditional way, and yes you will have many dead ends and works that stymie you or need a Black and Decker....No matter just keep making your work, stay true to your vision and your art will teach it all to you. You violate many traditional "rules" of art sometimes. rules of composition or color or value, but when you hit it right its spectacular. So I think you may be a bit inconsistant in production, but that is part of your process and journey.
One thing that is traditional is to make small studies first, like your file folders, and when one of them works well, then you charge into a larger work, not vice versa as you describe in the bittern. Making a larger work is not just blowing up a small work, it can still be original, the small work just gives you hints and ideas for the larger work
so keep on keep us inspired with your work, you are an amazing and original artist
