...A careful drawing, as befits his strong background in that field (with teachers of the stature of Folgueras, Magin Berenguer ...), a powerful mastery of color and choice of some elements of great beauty that transmit serenity.

 …A painting medium, pastel,  more than five centuries old, but in Spain is still largely an  undiscovered treasure, unlike in other countries (France, England, Italy ...) with a long tradition of painters who expressed their creativity through it.

A careful choice of colours, along with an elaborate technique  in  handling pastels, allow Del Riego to achieve the  varied and suggestive atmosphere  we like in his paintings.

 …Asturian and Galician landscapes, with its light sometimes more intense than it looks, but always suggestive and melancholic. Castilian landscape, with its strong and robust light. Portraits and figures, bathed in a baroque light that gives warmth and invites us to engage with them. Lights from the sea and the mountains, winter lights, autumn, summer ... All different, all masterfully reflected in his paintings

 …A luminous and suggestive painting, with vivid color and rich with great realism, without reaching that stridency that sometimes mars the work of so many painters. In short, pictures to be contemplated with calm, with that calm that dominates the mostly rural environments that Del Riego shows us in this beautiful exhibition”

"Lively, intense, realistic and above all, bright. This could consolidate the career of Del Riego "
