Here is the latest, I've done away with the clunky setup around the waist to try and make the robot more top heavy. I also experimented with some lighting on top. I cannot wait to get the hang of modeling, it's fun.

Here's a tweaked version of the last. Took off the shields to expose the arms some more.

Here from another angle.

Here it is with some arms, but still having trouble with the legs. At any rate I hope to definitely improve upon this once I get the hang of the UI.

Here is what I got so far, the hips need to come in a little more and the legs aren't to scale yet. It will look better once I tweak the color and make some rougher edges to catch the eye. Let me know what you think!!!
