In this design the main idea is to externalize the inner battle that one has to face in order to change one's character and defeat fears and demons. The best way to depict such an experience is the battle of St. Michael the Archangel against Lucifer, which can also be symbolized by a dragon. The purpose of such a fight is to keep the demons in the temple of sinners, namely hell, to keep them away from those who are free from sin and therefore pure. The technique with which such a drawing was made is dotwork, that is, a set of dots fill the figure to give it depth and the dots are more numerous in the shadowy areas. The time taken by me to produce this work is about 100 hours. The materials used are a sheet of paper (28 x 22,5cm) and fountain pens with a tip from 0,05 cm to 0,5 cm.
