/ic/ - Artwork/Critique

While seeing this thread, I thought I would try to find my old drawings to compare to how I am now. I realized 4-5 years ago I was very bad. (I'm still very bad, but I noticed a slight difference still) and my folders on my Passport external hard drive I have tons of images unorganized. So I'm trying to delete some trash drawings that I made and the rest I think I'll try to redraw them digitally later, but what I've been doing is starting to re-organized my folders and files because it's a huge mess.. So I have a question to you all, how do you organize a fan art image of let's say 'Black Cat' spiderman but drawn by a Japanese artist? (Pic related for my example)
