I will make not big comments but
Size= 3,5 meters wide x 2,2 meters height
Process= Wall decoration for living room. Interactive: clients' suggestions inmediatly incorporated to the design, no matter how crazy they were.
Materials= Wall, markers, Manley colours, hands
Any other question is open to dialogue :D I just can say it was my first time trying something like this, regarding size, regarding materials and regarding topic.
