A sketch that resembles the crest of a martial arts club. This sketch was made with Drawingpen, the duration for making a sketch is quite long, because sketching with a drawing pen requires daily care to keep mistakes in crossing out, because it cannot be erased like drawing with a pencil.
Behind this sketch there are also a few poetic words to complete the sketch, so that those who see it are a little interested. The poetic written there is (prayer is the key to open the day and the secret to close the night).
