I want to get some feedback in resonse to this arm that I built. Anything would be great. :D

Cool! We actually build a mini-version of our bot from this past year with a lego kit. We had to use at least 6 motors (several for shifting the valves on the pneumatics) and the 9 volt power supply to pump the air...
But it worked just like our bot did. We had our forklift on the front, and we actually stacked up a bunch of cups...
I would shudder to see what would happen if it met your arm though :)
Really nice!
