I always prefer to use items and markings that are more natural, or that I canfind some logical meaning as to why my character will have a certain item or marking that in nature would be unusual.
That's simply because I'm obsessed with realism in each of my characters.
That said, I find myself using some sort of large back marking such as German Shepherd and others like it, but I must say my favorite marking is the MM Husky face marking. (Can't remember its exact name off the top of my head.) That's the face marking non-preset Jackdaw has, in fact! (Last I checked. I always use his preset so I forget what he looks like to others sometimes lol).
When it comes to items, hmmm. This one is tougher as I don't use them as often.
I actually can only think of one character with items, and all he has is the crow friend and a bowler hat.
Aye, I dont think i have a serious favorite item.
But for the sake of amusement, it'd be the Car item xD
