There is nothing wrong with multiple versions of the same image. My ideas can't be seen from just one perspective, i work on something multiple times until i get more than one satisfying result. In the case with Avian F, the original has just over 100 views, and the SLIGHTLY changed version is over 500! Without these multi-versions, i am not satisfied i figured out the best perspective on a work. I don't just finish it and say "Thats perfect!" I finish it, and then say "Yeah, but what about this?" and then i make a new version.
