It’s a simple thing I did in GIMP. I don’t claim ownership of either the pickaxe design or the drawing, but i do claim credit for putting the two together. I originally didn’t want to upload this, but whatever.
 
I made this because Starlight Glimmer is my waifu, and it was disgraceful there weren’t any MC pictures of her here on Derpibooru. XD
 
This was inspired by a picture of Derpy with a pickax in her mouth in her mouth I found a while ago. If you are aware of the original location of the picture I am referencing, I will gladly put it here for credit.
 
My apologies for the blurry pickax, I guess. There was nothing I could do about that.
