"'Umbral 17', whose curatorship was left planned by Alberto Sierra with the intention of putting a magnifying glass over the emerging works of larger projection, is a trustworthy thermometer to measure the present temperature. This exhibition, without a doubt, corroborates a graphic flowering, fostered by engines such as Taller 7, the graphic art workshop La Estampa or the one lead by Óscar Jaramillo, amongst others. The dramatic elders of Juan Diego Trujillo, the frozen families of Llíam Roja, the mysterious birds of Alejandro García, the procacious bodies of Julián Cárdenas, follow that decidedly figurative line, which goes to the copy, to the portrait, to the closed contours and to the optical fidelity" (HKB Translation) --Page 11.
