This may or may not have been asked before- I don't know- but I wanted to ask about which horse, breed, coat, and gender (if there's more than one), you took to and bonded closely with (out of the three other horses you may or may not have sitting in your stables), even if it didn't have the ideal health and stamina cores the Rose Gray Bay Arabian horse.
For me, it's the Silvertail Buckskin American Standardbred (Mine's named Nuckelavee, after the fact he looks like he came from Undead Nightmare to me). His icy blue eyes may look "weird" and even "scary", but it looks pretty unique and even beautiful to me, as well as his coat color and mane/tail colors. It's quite easy to draw him if you're not the most detailed artist out there for brindle coats and whatnot. However, his timid and jumpy personality can sometimes be hard when you're trying to escape some grey wolves or shoot down a grizzly bear with a powerful shot from the Rolling Block Rifle from a distance.
Doesn't really matter when you have him at Level 4. Even if he freaks out, you can calm him down and keep pursuing after your target. As long as you don't get too close.
