It's actually really simple.

[1] All the images are free for you to use on deviantART only. If you wish to use it elsewhere, ask me first!
[2] Do not redistribute these images in any way. If you want to let other people use them, link them to ~guilpejon.
[3] Stock may be used for both commercial and non-commercial deviations
[4] CREDIT my stock in the description of your deviation.
[5] Leave me a NOTE/COMMENT when you use my stock.
[6] Don't just add a horse or change the colors of the stock and post it here, be CREATIVE!
[7] Have fun!
