I'm going to seem like a partypooper now but please don't use any of my photos for this, I don't want any of my horses edited at all and to be quite frank if Stan or Rian ever got edited then I would be very very upset.
I am aware that you should ask to do this. I don't mind people editing my photos but every time I "do my rounds" (go around drawing peoples horses) I always PM/Post message/ Leave a comment that I'm going to. Then before I go on and draw they PM me saying "Great!" or "Please don't" etc.....If they say they don't want me to I simply don't put the picture on the web/don't draw it it
