oh ok that helps! I'm creating a mural that is going to printed for my final show at uni which will be 4 landscape A0's in length and 2 landscape A0's in height! And if it took someone with your experience more than a week for this kind of work, then someone like me would be in trouble! I was thinking of using Flash because painting it in photoshop would destroy my computer! Haha Have you ever had experience printing these Flash designs on a large scale?
first, it took my a month to do my first vector drawing ( the lake [link] ) now it will take like 3 days.... flash is very limited for exporting huge format (flash was made to make website , illustrator to make illustration ), but if you want to keep working with flash you will have to export in multiple pieces then merge them in photoshop. By default you can't export bigger than something arround 5000*5000 75 dpi with flash. I hope this helps
