It is complete but not quite. Far too much happening to understand. I really do sometimes get out of hand making scenes too large to understand.
Though if you wish they are putting rockets on an Asteroid heading towards Earth. Will it crash, or will they succeed in pushing the Asteroid away? Either way, I quite enjoyed working on it. I must say a lot of effort went into many things in this image that may never be seen. Albeit I probably could add them here after finding them and rendering them later on.
