The selection of different penis shapes is diverse enough for R2CK's current state, but I feel like the female side could do with some variety too. Different vagina shapes such as a canine/equine look would be relatively easier, scalies would be fine with the current slit option. Perhaps an option to decide where breasts can be too? (Multiple nipples, different placement like the inguinal region for some hoofed animals)
Going forward, some more variety in penis shapes would be good as the species list expands. Not every species with a 'knot' looks like a dog's. Alternatively, a slider to control the smoothness of features like the knot and penis taper?
