Spider in the Basement

I started plastering our basement tonight.  As I was putting up the last tools, I seen this bad buy crawling around by my freshly plastered wall.  I grabbed the macro lens and wanted to try getting some shots.  I'm not thrilled with how it turned out.  I needed more lighting on the spider itself.  Extension tubes would have been helpful to get in closer as well... I might need to buy some of them :-)
