The overall feel of the picture is great... I love the concept and the angle. The lamp is a bit distracting and the shadow is out of place. With a bit of cropping, this could be one heck of a photo! :)
I don't understand what you mean about the shadow. It seems to be where it should be taking into account the lamp's base. Also, this might as well be a snapshot if it didn;t include the light source, which is rather a unique lamp at that.
I already cropped a good deal and like where it is. I am afraid if I cropped any more, I wouldn't have enough pixels resize and compensate for the crummy detail on the camera. :-)
