Hello, Blauer Jäger!
Design Notes

The first image below (artist: Nimrais) is a commission I've received that I feel best captures the physical form of the jackal I imagine. The second is a different golden jackal I found on FA a decade ago (artist: Rajewel) which I also found very representative physically.

Species: Golden jackal (Canis aureus)
Bipedal Style: Digitigrade
Nose: Black
Eyes: Reddish brown
Ears: Tall and prominent like Giacometti's, slightly more red than the primary fur color
Demeanor: Assertive yet humble; warmly serious; observant; the strong and silent type
Build: Though most jackals are slender, this one should have musculature almost like Caraway, thus strong haunches, chest, and arms; fur is reasonably short; features are sharp and jackaly; if compared to Giacometti, the muzzle should be slightly thicker along with lower volume cheek tufts.
Nudity Yes (sheath & balls)
Colors: Reddish gold primary fur (the hues that come to mind are those of autumn leaves); cream underbelly.
Additional Notes: If you are inclined to explore any novel artistic directions in the design to make the jackal more unique, I would love to see or hear your ideas!
