tutorial Billie Joe speedpaint illustration

This is a speedpaint of a custom illustration I drew for a client of her cat and her favorite artist Billie Joe Armstrong from Green Day and her cat which was named after him.
I used Photoshop for this drawing. And throughout the video, you can see what brushes I use, what steps I took during the process. I also I gave some tips I use while drawing.
Hope you enjoy it:)
