I'm pretty sure that this is my Krakarda beastie. (see also, my Charkadris mistake)

A custom Tyranid space ship. Drawn long before Battlefleet Gothic was introduced. You can see two other 'Nid beasties in the background; two examples of a very large unnamed ship, and several examples of small parasites that are spewed out in swarms ahead of the 'Nid fleets.

Oh, and you can see several Imperium ships too, but who really cares about them when there are EVIL SPACE BUGS preset?!
