Very nice Ghooge. If I may critique a tad? I love the B&W effect very nice. Also a great way to remove any discoloration from the incandescent/fluorescent lighting. However, I would either remove the items in the background (above the ammo can), crop the picture to remove those items, or re-frame the shot so the only backdrop is that awesome punched tin wall you have. I would go with the latter myself as that would make a nice background. I would not, though, make it a straight on shot of the background, try and keep the angle that you have now.
What style/type of camera are you using? If it is a DSLR then you can decrease the aperture number (increase the size of the aperture) which reduces the depth-of-field, or makes the background and foreground fuzzy and out of focus. If you have a standard point-n-shoot digital camera, then use some type of photo-editing software and manually make the back and foreground blurred.
