State of the SndBox monthly competition

Hello Picasso's children, this is my State of the Sndbox Competition entry for the monthly competition promoted by @sndbox. I have already participated in past months and this time my proposal is inspired by my beginnings when from time to time I painted one wall or another that time I really liked street art.

I made a small sketch to make the composition taking into account the available space and work the colors based on the rules of the contest.
