The art of vexeling and vectoring are interesting as each layer created goes toward the whole look of an image. It takes careful attention to the layering, and certain techniques to make an image that draws awe from others. I have gone through DeviantArt carefully and found several amazing tutorials for those who have never vexeled, or those who would like to brush up on their techniques. Some of these are Photoshop tutorials and others are for Illustrator. However, from experience, you can use the tutorials toward either program, or even the concepts to other graphic editors.
Please note that this form of art takes time and patience. I have been known to work on a vexel for over 7 hours, just to give an example.
