for all the artists on this forum:

It's probably just my own artistic shortcomings, but I never understood Photoshop tennis (now called Layer Tennis). More often than not they totally obliterate the previous work. This is why in Art Tag we explicitly state not to do that.

I guess it's a difference in perspective. Perhaps theirs is more about the concept, ours is more about the execution.

umm. I'm a bit confused.. interesting concept... but the end result doesn't seem to live up to the concept at least in teh example i looked at.
