Is Francis Ford Coppola a sellout? I'm sure he's accepted millions of dollars for his work. I'm sure he, as with many film makers, has many regrets and many problems and criticisms with his own previous works.

I doubt anybody would call him a sell out.

There is a bit of a ... shall we call it perception, or perhaps stereotype, that you have to suffer to be an artist. Doesn't mean you can't get the occasional paycheck WHILE suffering, right? You'll suffer the mental anguish of knowing your own criticisms over the prints you just made, and you'll move on and remember that lesson in the future.

Just like Francis. Look forward. You're done with that project. If somebody is interested in paying for it as-is, go for it. Look ahead to the next, and the next.
