Just doing so personal learning because I need to get better at drawing my beloved hoofy things. :P
Photo I copied from.
I claim no part of this as it is a copy of a photo I do not own.
notice how I said 'copy' and not 'reference'. Also notice how the photo I chose is under a copyright that permits me to copy it.
Stop calling your illegally made copies 'your' art and start following copyright law.
