Fluid Cloud (30x30x30 voxel resolution with texture) + digital matte

Obviously, the coloring on the clouds needs to be adjusted, but It can be done in post. I am focusing on matching the values and accounting for the sheer amount of distance in the shot. I am planning to add more clouds and place them father back in the scene so that the front clouds blend into the scene better while not losing their detail.
