I have never been accused of stealing someones art. When I was little I did trace rarely, I have a total of at most 7 traced images, maybe less (I'm one of those people who never throws away anything I draw). I remember while I was tracing I thought to myself: "Oh, so that is how it is supposed to curve" or something like that, and before I knew it I was right back to drawing on my own. I don't know why tracing didn't stick with me.
Of course that was before the internet existed. Also back then I NEVER, and I mean NEVER showed anyone my art, even if it meant drawing in the bathroom so no one would see me drawing then that is what I would do. I am a very shy person...although no one that knows me can tell. lol
Now a days I trace my own work when I need duplicates for something like shading practice, certain alterations I want to make, or when I don't want to damage the original by erasing too much, so I'll trace my work and let the eraser destroy the traced version until I figure out how I want the originals final look to be. However every time I trace my own work, I feel like I am short changing myself. I need to practice drawing as much as possible in order to get better, and that means I should be redrawing my work! I can't help thinking this while I am tracing my own work and so since it makes me feel horrible, I rarely trace my own work.
