This kit of the Corporate Alliance Droid is pretty basic. The most notable lack is internal detail on the model; much of it ends up see-through. I don't think this is a problem for the aft half of the body, but the forward "big wheel" needs some innards. There's also no detail on the insides of the smaller "tank drive" wheels and the tank's tread design is wrong. Another notable lack is a usable paint key on the instructions. Sure, there's a table of colors, but few, if any, of those colors are needed for the model and there are no color callouts on the assembly diagrams.
