"My friend Yuri introduced me to Juan. And then, half an hour after [...] by the sea, in the sweet light of the twilight, we were all three having a beer.
 
Juan asked me some advices, and we improvised a coaching session. Afterwards, I told him about my book. Spontaneously and sincerely  he offered to illustrate it. [...] His outstanding talent has led him to exhibit in spaces such as the Fresh Gallery of Madrid or the Bilbao Exhibition Centre.
​
[...] As I was meeting Juan, I saw more and more similarities with Leonardo Da Vinci: some that I can’t tell, and some that are just obvious. For me, Juan is the Leonardo Da Vinci of our era. A modern classic. A genius."
