Sunset on the walls is an oil painting on stretch linen on a beech wood frame. In this painting Luis Rincón finds within this constant pictorial search the textures, forms and light that configure the idea of an individual vision that the artist has about the perception of the landscape, the landscape perceived as a state of mind where the observer is reflected, and is then observed in the mirror which is the representation of reality. It is the light color of the walls of the different planes the reflection of the sun, but at the same time it is the reflection of the artist and the observer, who in the exercise of the gaze, completes with his particular gaze and mood the image he sees.
