This is a classic example of Shantell's main work and style. By the looks of this picture she is drawing on a huge brick wall possibly out in the streets. I like how it looks like she first drew a large squiggle then made things like faces out of it.
Another example of Shantell's work is this piece of artwork that has "you" written lots of times and all are crossed out except one. This is the kind of artwork with a hidden message in it which I guess means to be yourself. This was part of an art range that Shantell created called "who are you?"
Shantell seems like a very inspirational artist who is using her talent very creatively and is very inspiring.
