Actually i don’t like watch series or movies because i spend my time in another things , i play FIFA online in Play Station 4 since 2014 until now, and also i play every week in competitive mode with my friends and people from other countries, especially brasileans and chileans, but sometimes when i am boring to play Play Station 4, i try to do something different as watch series, draw or paint. I really like to paint and draw, it's in my family's  DNA, my brother is a tattoo artist, he makes graffiti and murals, my mom paints mandalas and pictures of animals, then i will show my works.                                            I painted this picture in quarantine, with tempera and watercolor, the  interpretation is given by the viewer.                                                                                                         T his picture  is about psychedelia and the transitory of life.
