Mr. Costantino is indebted to these clients – mentors for encouraging superior standards of imaging architecture.
As an architectural illustrator for over forty-five years, I have provided a national clientele of distinguished architects with striking & award-winning illustrations of projects around the world. During these professional years, I have also developed my watercolor painting to an accomplished level, and capture urban scenes, landscapes, homes, and portraits in a plein air, or a direct, alla prima, colorist style.
