Sunkiller Potato (I think it should be here...)

Me and a friend (namely Gorea) were musing about the archeotech relics and somehow stumbled onto a sunkiller potato. I, being totally bored, decided to produce this stunning piece of inspirational artwork:

Took 13 minutes to do.

You need to work on your anatomy. What is that, a fish flying in the sky? why is it blue if its a fish?

And those Necrons on the left are terribly posed. I'm amazed their spines are one piece.

They Grey Knights on the right are equipped with completely illegal gear. Since when can a Grey Knight carry a Shokk Attak Gun?

And that Monolith in the top left corner looks utter crap. Do you even know where to find necrons?

Why "Sunkiller Potato?" What does it rep from the rulebook?
