Damn.....that sounds interesting...
But one point is still tricky, if i finished one step of work i´m sadified with i can decide to let it rest this stage, or try to work on and endanger the whole work. Like lineart ant than a shading.
At the moment i can come back to evey stage of work i wish. Sometimes i´m not realy sure if i´m happy with the result, then i can watch both paths and decide.
....Not that i got money for bringing you to digital art
