Not being 100% satisfied with my first pumpwagon attempt, I broke it down and tried it again. With the help of many bits from a recent gamer's sale, I was able to put something together that feels more orc-like:

I may remove the standard but am not sure...I may also remove the spikes on the side of the left pumpwagon. They look like guns to me:

The trick will be to somehow get snotling models for the crew.
The same gamer's garage sale allowed me to acquire the proper bits to make a good Big'Uns unit. In addition to jaws and shoulder armor, I placed some plasticard under their feet so they appear taller. Normal Orc, Big'Un, new plastic Black Orc (thanks Marc!) and Grimgor on the end, just for comparison.

The Big'Uns ranked up. I'm excited to paint this unit as I think they'll stand out nicely.
