Disregarding the fact that this seems to be an entire planet instead of a comet (which are much smaller and chiefly made of ice), a comet that's nearly as big as earth would actually be nearly completely round, thanks to the effects of gravity. I mean, look at Mars, it's basically the same size. :v
That besides, there are a couple of things that bother me, partly as a fartist and partly as a former geology-student:
1: Earth's crust probably wouldn't crack up into neat unharmed chunks like that, especially not on that scale. The crust (which is the part that could feasibly crack and shatter), at its thickest, is still less than 2% of Earth's radius. On "our" human scale, it most certainly would crack and shatter, but from space it'd probably look like the comet smashed into a giant ball of semi-molten sand.
2: That dust behind the comet, how on Earth did it get there? It should probably rather be shooting out in a huge funnel shape that's centered on the impact.

But with that said, this is still pleasing to look at, so keep it up! I have a soft spot for planetary collisions. :v
