imp anatomy mini lesson (Patreon)

penile anatomical variation is the equivalent to a unique immune systems, where it indicated genetic variety and therefore more preferable. this especially can be another indication of regional differences between imps as genetic variations can be more isolated to certain areas, ergo regional indicators. this along with horns and certain eye colors and tail types can give a fuller picture. when imps made more efforts to unify, especially in the modern age, less and less of these differences can reliably indicate a region. however trends still occur.  anyways, have this little sketch of little imp lads

due to the variety i want to make more of a chart for male imp variation, and ponder over female imp variation.
