You can change the Custom however you want (change colors slightly, add/remove wings and horns), but not to the point where it's unrecognizable from the original design.
If uploading the character on Toy. House please be sure to credit me as well, I'm "Hope-of-Morning" there.
Don't Try to Haggle with me, I won't accept art Art offers Unless I state so.
DO NOT RESELL, IF YOU GET TIRED OF SAID CHARACTER/S PLEASE RETURN THEM TO ME SO I CAN KEEP TRACK OF THEM AND FIND THEM A NEW HOME
DO NOT USE MY DESIGNS IN RULE 34 RELATED ART. (I'm willing to "negotiate" Though)
You Can ask for the Original File in the comments, this is JPG to avoid theft and recolors.
