Ana Gomez studied fine art at Salamanca University, but was always looking for a way to express the ideas and little characters in her head. Illustration was that door and now her drawings spread the humour and joy she feels inside. Ana draws lots of pencil sketches and then works them up digitally. She lives in Madrid, Spain.
