At that time, the watercolourist felt like starting again and doubted on the artistic quality of these early pictures, hence he signed under the pseudonym of "Masca". In 1975 he began exhibiting with the "Agrupación de Acuarelistas Canarios" (Canarian Watercolour Association), first in the art gallery Cairasco in Las Palmas de Gran Canaria and one year later at the Fine Arts Society in Santa Cruz de Tenerife. In 1976 he exhibited again in the above-mentioned Cairasco gallery, where he won the bronze medal of the Association for the watercolour entitled "Árboles y bruma" (Trees and mist).

He knew how to capture with great sensitivity the environment and the atmosphere of yesteryear, leaving a documentary record for future generations, as no other painter of the time devoted to immortalize and portray the city to commemorate such an important event in the Canary Islands history. Until the arrival of Comas Quesada, except for certain paintings by Nicolas Massieu, Felo Monzón, Jorge Oramas and a few more authors, Las Palmas was a city without painters who portray her. And if Massieu is regarded as the painter of Gran Canaria, Comas Quesada is the painter of its capital city, because until then no other artist had produced so many works on it. This is the reason why he is known as "the painter of the city", he was a kind of historian, a "pictorial chronicler." For those pictures in particular, he sacrificed his usual technique by glazes and a certain
