The Calma and Sossego themes are commissioned works from Brazilian artists Aline Bispo and Naia Ceschin. Resplendent in design, these themes are accompanied by Bossa Nova vibes, background music and sound effects that further immerse you in Brazil’s vibrant culture.

Inspired by Brazilian nature, I developed the artwork titled Calma with the intention of sharing with the world a little of what Brazil is and its connection with Bossa Nova. To convey the connection between the tranquility of the sea, our natural and cultural beauties, in an organic way, through the strokes, welcoming the browser user.

This project is very much connected to what I like and how I enjoy drawing. Landscapes, colors that bring tranquility, and scenes that playfully blend plant and animal beings.
