dA Finisher and Polishers - A novel concept?

I have an idea for something that I wish existed on dA (or anywhere for that matter).

How many times have you looked at a decent piece of art, critiqued it in your mind, and knew exactly what it needed to be better, or even, dare I say, perfect?  Conversely, how many times have you created a piece of art that you knew was decent, but you also knew that a master out there somewhere could make short work of it - perhaps even with something simple, like a few well placed strokes?

We already have the two-step coloring concept, as with the , where the line artist provides the skeleton upon which other artists 'improve'.  The line artist submits art to the color-me-club with the express understanding, even agreement, that his or her line art is there for others to color.  That's very cool, because it's a collaborative effort of sorts, one that is open to interpretation, gives rise to Creativity Within Set Boundaries, and produces some amazing art seen here on dA.  Likewise, we have photomanipulators, who take stock or other people's work and make it into something new, while giving credit to the sources.

My thought: what if this was taken a step further?  What if a piece of so-called 'finished' art was subjected (again, with prior agreement and understanding) to yet another post phase - a "finishing"/polishing phase.  So, for example, a line artist creates a skeleton, and a color artist takes it as far as s/he can. At that point the color artist submits his/her piece for Post work, by anybody who might be interested in taking their work, their interpretation, to a whole new level.  

Post work, as a concept, already exists throughout industries everywhere, including art industries, like the motion picture and comic book industry.  But it doesn't exist on dA (of which I am aware).

Now, understandably, many artists don't want their art messed around with, or altered by anybody. But many do, and I am one of them - if nothing more than to see what was possible, to see a piece of art go to further fruition, and perhaps even learn from that.

For example, I just finished this piece:



I worked very long and hard on it, I love it, I'm proud of it, and it's doing well in the competition color-me-club.deviantart.com/j… for which it was created... but I'm not happy with it.  I worked to the extent of my limitations, and improved my skills considerably in the process, but I also know that a finisher, if s/he wanted, could take this piece to a whole new level.

And that brings me to my thought, my idea: What if there was a group established, one where people could submit their 'finished' art for post-work, or polishing/finishing by other artists who have a talent for such a thing?  It would be just like the lineart process: you'd give credit where credit was due, but the new/post piece would be yours (subject to the approval of the artists in the chain of creation, of course).

I think I will create just such a group.  One where people can submit their art for post work by others.

Any thoughts on this, anyone?
