Let me start by saying, great paint job (xcept for the big silver.... thing...)
However, I would like to point out that, while the splatter effect is well done, its a bit misplaced.... being an offroader, I've learned that if you want a good mud splatter on the side of your vehicle, your tires must extend past the side of your truck... and since the tracks on the tank are not only inset, but covered buy the bottom of the armor, very little mud would splatter from them. However, where you would get splatter would be on the top rear, from the rooster tail.
but like I said, still a good paint job
Great job! I think the only thing I would do, is add some very fine glue lines to the silver part, and wash them with black, then highlight with gunmetal...simulating where the tank was struck, and the techmarine welded it up. Then perhaps a dark wash of tinbits and black to simulate the discoloration from the heat of welding it.
Nicely done!!!
