Thanks for the comments. I have not weathered over the crosses yet. I'll be getting to that soon. Meanwhile, the weathering is done with oil paints and Mig pigments, and the base color is Tamiya's dark yellow spray can. I don't have an airbrush here, or else I'd put camouflage on this.
Here's a mini update: I put one set of spare tracks on. They are painted Tamiya flat black, then dry brushed with metallic gray and treated with Mig Pigments. I'm probably going to put another set underneath the gun. The sword is from a Tamiya Japanese infantry set that I'm also working on.

The next steps will be installing the wheels and tracks, then the accessories, and finally finishing the tank crew, which are the original Tamiya ones that came with the kit. I'll keep posting photos as I work on this.
