The shape here is very interesting, but I don't care for the rotation within the frame. The points of the square crowd the edge of the frame too much. I would have preferred to see it with either more negative space as you have positioned it, or to have it rotated 45 degrees within the frame the size you have here.
Not a clue what this is but I sure like looking at it. I can't even tell what it's made out of...wood? 100% on the challenge, and a good shot, with good lighting. I do like this. 8 from me.
