Using a white pencil I did a value study. I used black to add some details. I used a scrubber to smooth the pencil and stik tak to lift. We will add further details and be able to adjust values more as we add color to this.
Using the same colors that we used for melting with the addition of black (or gray) and white and dark brown (you can use indigo, black, or black grape instead of dark brown). I added shadow and highlight to the stem, shadow and highlights to the mushroom and the white spots. White is a very useful color for of course adding highlights, lightening areas, changing colors in an area, adding texture, and fixing things.
