To prevent the model from sinking into the floor at all, the author placed him just above ground level to prevent the mesh from clipping the plane and at the same time, not appear like its hovering. As seen in the above pic, the crouch animations were well suited for MassMouth too. With his body dimensions the way they are, a crawl was the perfect locomotion while crouching. Smooth and extraterrestrial-like, this sequence also brought out a good chuckle. The model is however a bit stiff looking at times, but over all Stephen did a really nice job animation.
Movements are nothing too unique or spectacular,yet they are clean, uniform and well carried out.
Detailing on the skin is rather nice though, colors are dithered and blend rather well, and unlike other models, they don't look washed out in Open Gl mode. CTF skins are just a re-colored version of the main, with no real change in detailing. Mapping was extremely simplified and very wasteful. Basically it is laid out as a front and rear view map which could have been optimized a few different ways. The best, IMHO, would have been mirroring the left and right sides of the model, since it is a symmetrical form.
