Blue hair girl = The one being drawn
Black hair girl = Reference pose
Blonde girl = Facial expression
The blue hair girl will be wearing the black top from the image where she is being fucked (breasts will be exposed) and the black stockings from the image where she is not being fucked. She will be in the same pose as the black hair girl, however, she will also be sucking dick from a hole in the wall where the black hair girl's left hand is. There will be cum from the blowjob like the blonde girl's image, but also on the blue hair girl's breasts.
Also, the mirror part MUST be drawn as well. Background can be artist choice and the message at the bottom of the drawing will be instead: "Naughty boys who want a piece of this ass, come to the stables ;)" You don't need to draw the character icon next to the message like the reference pose; the font, style, etc. of the message is up to you.
That's all of it, thanks.
