He has been exhibited widely--so widely that listing them here is just not going to happen. You can find out more at his gallery, Fredericks & Freiser (New York).
These are pieces that do not suffer photography. You have to see them to see both how they look from a distance and close up. There is the whole and then there are the details.
Also shown by Fredericks & Freiser is work by Mark Thomas Gibson. His Westward was an interesting, colorful, counterpoint to the pieces by De St. Croix. But it isn't all about the color. Look at the texture in the black part of the piece--visible even in the photograph below. It looks almost haunted and haunted is good.
