You are right... I think i have to "polish" my pixels, yes, it's true... That's my problem... When i have more or less the idea i want, i stop working on the picture, when, how you said, i must terminate it polishing that scene... it's the "hard work"... And at the same time is the work that give more realistic appeareance to the scene...
Your edit of the section is great!... thanks, i will try to work on it...
But... what do you think... It's better change character colours, or, how Helm said, work more on background?...
I think, Helm is right...
