This is the basic stages of almost every digital art of mine.
first the rough sketch after some thought, then the lineart wich i like to draw clean.
On paper my lineart is really dirty, but on digital i like it clean.
Then the basic colors, usually in a darker tone, then the rendering wich is a long process with a lot of good and bad decisions haha.
And i usually finish the piece with some lights and shadows, and try to smooth everything that looks weird, then i save, close photoshop and never touch it again xD
