We are on similar journeys. I'm discovering also the value of collecting ones own backgrounds for later use. Composites are a lot of fun and take a lot of work and learning. Weather or not it pays off is the question.
Nice concept very well put together. I find it a very hard exercise to imagine how to put a puzzle of various images together, and then of course actually putting the pieces in place doesn't often work smoothly. Time consuming too, for sometimes very few sales... tough learning curve but can be a lot of fun.
