After printing the photos on 8'x11" paper, I tore out my favorite sections from each individual scene, and created a collage. A background of white gesso with a covering layer of blue paint for the canal and sky was used on a blank canvas. I sketched the final composite scene with a black sharpie directly onto the canvas. A darker layer of blue acrylic paint was used to cover those areas where I decided to change my lines. Here is a close up of the center section for the start of the painting.
This was followed by a rough overall foundation of colors for the base of the scene, with details starting to be filled in.
Next I added more detail to the faces, water and bridge - leaving the buildings in a more sketched rough appearance for contrast....
Deciding when to create a completely new artwork or when to change an existing one is part of the process we all go through in both art and in our daily lives. Though there is always the pressure of projecting what others think of us or our work, it's important to be true to our own needs and values.
Make priorities, do what you can in the time you have, and hope everything will fall into place. Then remember, as is often heard - "rules are meant to be broken", and as I say, "sometimes decisions are meant to be changed"!
