Madrid artist who bases his creation on fields that may well seem different and even opposite: analogue and digital. The first refers to the most established and accepted conception of art, that is, one who works with the canvas, the brush and makes paint. In the case of Heras, this art approaches abstract expressionism or even Informalism, but the truth is that it cannot be typecast in any waterproof category, it is necessary to speak of the creative process of this complex binomial. The other field refers to digital work, generated electronically and with multiple origins: paintings from different periods, photographs, graphics and digital illustrations, programming, etc. Everything is valid for digital creation, as this arises from a good work of collection, improvisation, selection and mixing. The artist thus performs a constant search for the unique element capable of generating an exclusive composition and its consequent millions of unique variations, could be formally defined as digital dynamic abstract expressionism, within the post-digital current: the pieces will be mixed again and they will enter a kind of imperishable and virtual creation loop.
