Mudbriar is a very simple character in means of design, much like his girlfriend, Maud.
Given his occupation, i see him being a fairly 'grubby' character. So i made him a bit more fluffy and added a few additional markings.
His cutie mark added some nice additional colours to his design and weren't used to that advantage.

So i did it myself.
I also like to think of Mudbriar, as a character who always has a bag on him to store something that catches his interest.
And seeing as he is a very knowledgeable pony, i like to think he has a quirky collection.
So i had him begin a pin collection on his bag :)
