Steve, I feel sorry that you received no answer till now. As far as I am concerned, the silence did not mean that I feel your model is bad, it is simply that I do not like tanks in general, just airplanes (and even feeling guilty that they are often military planes).
As a modeler, I can say your paint and details handling is very good, I cannot say much more, sorry : I just friendly hope that tank lovers will confirm you made a good creation.
