This is a really nice work in progress. The pics surely does not make justice to the level of detail that is necessary in this vehicle, as I managed to obtain scale drawings (well, in 1/35, but could be reduced properly

) and the crane, i.e., is very rich in details.
A little question: what is the color scheme that you planned? I wish to finish my future M31 (Hell, I have to finish my current-but-yet-not-finished ones previously

) in one of the eye-catching schemes with one or more camouflage secondary tones. I think that your excellent work could be finished superbly in a camouflage scheme. Happy modeling!
