Artistic Science

I hate to be a bother, but I was wondering if you can repost your tutorial you made a few years ago about which images you find on Google are free to use and don't have copyrights. This will be really helpful, because I am trying to look at photos of wildlife animals so I can practice drawing them and getting their anatomy right. You are a huge inspiration to me and I hope to become as good as you one day! As always, keep up the fantastic work! <3
