I started with the lighter green and dipped my sponge in the bowl (used a rubber glove here) and squeezed out the sponge over top of the statue to let the diluted color run down. I did this several times with this color.
Next step, I dipped my sponge into the darker green and held my hand over the statue again and squeezed. This diluted color runs down the statue in the same way rain would over the years.
I don't show it here but the last step I drizzled the diluted brown over top. I wanted to knock down the color of everything and dark brown was perfect for that. So squeeze this last color over the top of the piece.
