Good lighting and theme presentation, but I don't like the out-of-focus beam in the foreground. I find it detracts from, rather than adds to, the overall shot.
Great weath of triangles. I like the variations and the light fixture as an additional element. I'm not keen on the foreground beam (I played with the frame and cropped it out with my browser and prefer it without it). Also, your highlights are blown out in the lower right corner. 7
