Anyways, I was so fascinated by his work and characters.
(Andy K - wall piece at Spike, Dresden)
He used a lot of mixed techniques - paint, paste-ups, spray, newspaper collage etc.
He did this piece during the workshop reusing a huge canvas (unfortunately I only have this small picture:), called 'Thoughts are free'. Here's a small demonstration on how to use the paste-up:
Optic ninja
Santa
I 'stole' a small image of a personnage from the sketchbook he used at the workshop. Nice one, huh?
More collage & paste-up during the final day of drawing @Blue Fabrik:
Andy's Cat
& Granny
