Sentinel Interior

Interior of the Sentinel is nearly done, time for assembly. Here are some pictures to show color scheme and progress. I have no idea what the outside will look like, but am happy to take some suggestions. I am thinking to go with a US WWI scheme to match the IG units' color scheme.  Any idea what a good US WWI tank green is?

 

I went with the idea that the IG would be industrious given the volume of troops they support and that brought to mind government contracting and the industrial gray.

Comments welcomed.
