This is so much fun... and I kind of love this little guy... :) Or, he is not that little... The painting is 50x65 cm, which is approx. 19x25 inches.
I don't know if he is finished and I don't know how I know when he is finished... :) I think the solution is to start another painting and go on playing and practicing.
I mostly used acrylic paint, but also crayons, pen and pencils.
