I've chosen the colors and her name after the brand of my backpack for this girl, her name originally was going to be Packback, a reversal of backpack. I was trying something new with shading and have been attempting fur shading as well as being a soft cell SAI user I realized that I need to buy the full program to get the details. My first attempt failed, tried to use the celpen,

I'll post images of the backpack later and have to admit I am spot on with the markings.
