Tyrex in acrylic

Travelling through a Wormhole, was the theme for today "daily sketching workout"

I started sketching random ideas with a pencil, but nothing came. So I decided to sketch with acrylic.
I used a sponge brush and painted a yellowish background colour.

Then I took a really messy and damaged brush and made undistinctive shapes, randomly...

Then a Tyranosaurus Rex appeared in the mid-ground...

From then on it was  a race to try and capture the vision before it vanished...

I used three brushes and acrylic paint.
