Great spider picture. The problem here is the challenge is "Straight" But the web is out of focus. More DoF or focus on the web and kick off the (REALLY REALLY REALLY )ugly spider.
IMHO this is great photography and I would have given in to the temptation to enter it too BUT the focus of your subject(spider) aren not straight lines. The web has straight lines but is not the subject. A real pity because in another challenge I would have voted 8 but I cannot on this pic therefore I'd rather not vote. ( I cannot give you a low score either!)
