It used to happen to me because I wasn't putting effort into it and I was just taking ideas from the characters I saw in-game. However a few months ago i started to really put some thought into my character, And using items and such I created a basic character which a lot seem to notice and pick out from the crowd. I am actually now surprised that people 'like' it and sometimes I even get these annoying whispers saying "Lovely character, how did you make it?"
Lol, well i won't say how I made it because I'm bad at explaining and whispers have limited characters so there is only so much I can put and i'd be there forever explaining. However I can fully say on here that-
I think of a random yet 'natural' colour like from a timber wolf and try to meddle with the colours until I find a desired one. After that I try to find a suitable marking to go with it and also meddle with the markings color until it suits the pelt and underfur. I find that making my characters eyes cyan or blue, gives a certain feel to it.
But that's all that I can think of... xD
