Here's how I would rank potential picks. There's no merit to "good" and "bad" as it's based on what animals I like or what would fit any of my current projects.
Realistic bad picks: Indian Leoapard, Golden Jackal, Jungle Cat, Indian Wolf, Mugger Crocodile, Chinkara Gazelle, Smooth-Coated Otter, Tibetan Fox
Unrealistic bad picks: Rhesus Macaque (or any other macaque species), Siberian Ibex, Hoolock Gibbon, Indian Porcupine
Boring neutral picks: Asiatic Lion, Himalayan Serow, Sambar, Chital, Barashinga, Gaur, Yak
Fun neutral picks: Nilgai, Great Indian Bustard, Malabar Giant Squirrel, Golden Langur, Slow Loris, Indian Pangolin, Pygmy Hog, Fishing Cat
Realistic good picks: Blackbuck, Red Muntjac, Hanuman Langur, Himalayan Musk Deer, Hog Deer, Himalayan Marmot, Himalayan Monal, Indian Gray Mongoose, Four-Horned Antelope, Sarus Crane, Temminick's Tragopan
