Hand painted art.
Digital art may be sharper , but hand painting has a more human touch and warm feeling, with a natural blur.
Digital art can be duplicated, but not hand painting, which makes it more valuable, each piece is unique.
It requires drawing ability that can't be faked.
It's presented without CG effects for easy comparison with the left illustration. It doesn't have natural blur like hand painting, but it's easy to change and redo and a large variety of CG processes can be used that give it a great capacity for creativity.
