Silvino González Morales shared a quite beautiful post on graphic design featuring a set of abstract illustrations titled Espectros. The idea is simple, it basically blends shapes with a radial gradient. However the composition makes it very unique. As the wise man say, the simple things are always the most difficult to achieve. Silvino proved that to be right. I wouldn’t mind having one of those in my house.
Each one has its own bias, its own weaknesses. As a designer one of my weak points is simplicity, I tend to have a great difficulty with minimalism (and I love so much minimalism). So I try constantly to challenge myself and improve constantly. All these series of designs for different projects have in common that effort for create outside of my comfort zone.
