Amendola is considered one of the best watercolor painters of the Modern Era in Mexico. He died in his home on the night of August 21 of 2000, from pneumonia. He achieved great status in the art world for his beautiful representations of landscapes and popular life where "El Tepozteco", one of his most notable works, became the symbol of Tepoztlan. This place became so important to him that he lived there for many years. According to his wife Sarita Felix, his personal staple was the people and places that represented Mexican culture, and it was his daughter Gloria who was to be his model. He was awarded for his work in Mexico and abroad. His artwork became known in New York, Houston, Los Angeles, Guatemala, Japan, Korea as well as Mexico. In his spare time he would draw cartoons satirizing himself. His friends described him as a "bohemian at heart" and great artist.
