Here's the picture I've recently finished with some sketches I'd done beforehand. I really like this way of planning out an illustration, so that I could keep track of things! Also I made all the elements on separate layers so that I could work with them faster and then added the border effect to imitate lineart. The process was almost perfectly smooth for me, except my program - ArtStudio Pro - started lagging horribly during the last steps. So, it's better to work in portions with this method, and the rasterize and merge your layers lest the file gets too clunky ^^"
