Well, if you're happy, that's good. But you've posted for the world to see.
I'm not sure what look you were trying for, but the material really doesn't work. If you want to indicate dust, try going with chalk pastels. They will blend better and give a more scale appearance. If it's mud you're after, the surface should be smoother, darker and shinier for fresh mud and smoother and cracked for dried mud. The dirt/mud is all over everything, including the interior of the hatches and the figure, but the floor is spotless.
Also, when applying your ground work, taping off the base will provide a nicer looking display so you a nice even demarkation line.
