Greetings, I show you the step by step of this ball with teeth, in the following image I show you the final drawing, even with full resolution you can find it in the pixEOS art gallery:
I used a software called Medibang Paint Pro, the first thing I did was the lineart, I used the "pencil" brush and made the contour of the ball, the mouth, teeth, tongues, the eye and some details.
Then I concentrated on shading the teeth with the "pencil" and with the paint can fill the inside of the mouth in black.
With the "pencil" I also slowly draw the shadow of the ball, only with small lines being very patient, to give it more darkness I proceeded to make more lines but in another direction.
This same precedent of the shadow of the ball I applied it to generate the shadow of the ball on the floor, which although it is not drawn if the shadow of the ball is shown.
I proceeded to create a layer for each color and use a "muted watercolor" brush to gradually differentiate each layer, starting with the teeth.
In this way I was coloring the ball with teeth, in the following images I show you some stages of the process.
The final work is this, you can see a few small drops coming out of their mouths, I drew them with the "pencil" brush trying to simulate a few small drops of slime.
A look at the #pixEOS art gallery
I hope you like this drawing. Until another chance.
