The photo has a late night "surprise!" feel to it. The colors and detail are muddy and the lighting too dim yet harsh. But your composition is solid if those oher elements were fixed - I like how blocky the frame is laid out.
Washed out. The vertical lines split the picture in an unfortunate way IMO. The subject seems that can not balance the composition. The shadows and the spots on the background are distracting.
Unfortunately this is one of those shots that really doesn't 'speak' to me. I don't like the overall hue - I would have preferred this in color or in a less purply B&W (keep in mind that my monitor may differ from yours). The highlights on the right hand side distract from the spider, and while I know it's difficult to capture them sometimes, the spider would have been much clearer had you been able to catch it sitting still.
