I held a vote amongst a couple of friends on the idea of changing my 7 species' from having human-like feet, to instead having monkey-ish feet/paws. The vote was unanimous on changing the feets to peets, so after a bit of sketching, here's the final results.

Their peets have a thumb (though not all the species thumbs' are opposable, namely only Sancers, Ruhhips, and Mimiks) and mostly line up with their evolutionary path, such as Okupits having broader soles for traveling on sand, Sancers having webbed peets for swimming, and Vaucu having flatter toes for sticking to walls.

That's enough feet talk for a couple years I think. You may see me updating past art to reflect these changes.
