Overall, I think its a great model ... but you really need to take it a step further IMO.
The very dry dusty effect is great ... really well done and realistic .... but then the tracks and running gear have very wet mud ... like it ran into a peat bog ... which can happen. You just gotta show it to give the complete picture and why theres 2 finishes! And donīt be afraid to add a little more splash as the fenders are off ... not too much ... but enough to give that effect.
