Shells on Pink in Progress

I'm working all around the piece, I've decided to put the colored shells in first and then add the background pieces that are in shadow or in shades of grays. The color is more fun to work with. I like the subtle softness of the shells in the first layer of pencil before I add the solvent and deepen the color. I plan to try a similar drawing of shells on another surface in which I won't use solvent, just pencil and let it be very subtle. I've started working with the solvent and colored pencil in the upper right and you can see how bold the colors become.
