I go to WindowsC: --> Feral Heart folder --> My_Presets
In the folder Preset_9, there are the preset guidlines that I downloaded off deviantart. I used those to color the preset and then exported them into the file named Preset_7 (I tried Preset_8 folder but that didn't work either).
For example, the right side of the body guidelines is labeled YourNameBody_Right. After I colored it, I named it IvyBody_Right, and I exported it from gimp file to a .jpg file. Then I went onto FH preset maker to make sure there weren't any errors in the coloring but it wasn't in the Preset 7 tab. I also downloaded a friends preset to be able to see it but that's also not in the preset maker on FH. I put the friends preset in the Preset instead of My_Presets, because that's what I was told to do.
I hope I answered your response as you wanted /)^(\
