I want to nominate my favorite artist in Mexico: @safosone
Even though his art may look simple and even childish I think it is a great and fresh style. I used to live in the same city as he does (Torreón Coahuila Mexico), and it is a city that was beaten by violence and war drug, so it was really refreshing to walk on the street and see all these lovely colors, or even a lamp post or flower pot smiling to you. His art helped the people regain trust on their city, and eventually go back to the streets without feeling fear like we did for many years. He is the most humble and kind artist you'll find, so I really really think he deserves to gain more recognition.
