I like how the artist began with the design concept of a guitar but strayed away from that and created a scene with it. I think the simplicity of the piece allows the guitar to still be seen. I love how you can see both the scene and the guitar easily.
Svatmarama, Hatha Yoga Pradipika ~ When the breath wanders the mind also is unsteady. But when the breath is calmed the mind too will be still, and the yogi achieves long life. Therefore, one should learn to control the breath.
