I have just finished up art for a Cirque du Soleil "Alegria" performance. The original painting started out as a 30 x 60 acrylic which was shot and scanned in and finishing touches were added with photoshop and painter. The working file was close to 2 gigs before it was finalized and flattened. The reason the working size was so large was the the art was printed out 7 feet wide by 16 feet tall and hung outside promoting the event. Always a treat to see your art blown up to huge sizes.
Here is the art without text...
and close ups.....
