Hi! The reference sheet is the image also used in the HTML layout, and can often be found around the more recent images in the gallery. If you're unsure what reference to use, please feel free to ask me!
If I sent you this folder and didn't say anything about picking from only primary then feel free to pick whoever from whichever folder!! Less art doesnt mean I use them less, I'd love any art of anyone!!
P.S. you can see who are in the same groups using the tags!
