The Teeth and Tongue
Draw the shape of its teeth using #edd8af color. This is your ‘teeth layer’. Add a ‘right fang’ layer, we’ll draw it later on a different layer behind the ‘teeth layer’.
Then create a divide on the teeth with the #b23b10 color. You can hide some layers in order to get easier tracings from the pencil sketch.
Give the divide a shadow like below.
Create the ‘inner teeth’ shape layer in front of ‘teeth layer’. Use white (#ffffff). And then add dark sides to the inner teeth. Create a new Clipping Mask layer named ‘shadow’ in front of ‘inner teeth’ and paint it with soft black.
Then bring back the hidden layers.
Add shadows and highlights for the teeth.
Create the ‘right fang’ behind ‘teeth layer’ and add highlights and shadows to it.
Apply a motif on the ‘left fang’. For the inner motif use #957648 and for the outer, use #c4bca7. Then add stroke with this colour #957648 for the outer part. See picture below for reference.
Create the shape of the tongue. Draw it behind the gum and teeth then add highlights and shadows to it.
Create the hole of mouth. Draw it behind tongue and color it black.
Manage them by grouping.
We also need to add highlights and shadows on the head.
