• A work where you spend two weeks doing it is better than another one done in only five minutes???

• The joint bends bad, the hair doesn't look good, so you spend many hours in Photoshop correcting this. Meantime you forgot that the whole figure doesn't match the background image used.

• You use post=work to correct some error, but in a purist sense the error still exist and the correction process introduce new errors. The question is, the sum of these new errors is better than the original error?
  The only way to not create more errors is to not do the original error or at least make it not visible!

• Errors are part of our life, world is not perfect and is full of imperfections. A perfect 3d sceme looks artificial.

• Why do you look at a Greek statue? It has no arms and in most cases has no head, so it needs some post-worked head!

Stupidity also evolves!
