Faking it.

 Not much painted this weekend, just two Cerastus Knights from House Perdaxia.
Speed painted with contrasts.

Though the decal sheets that come in the retail boxes don't contain the House Perdaxia coat of arms so I've had to either buy a sheet of House Fureans decals from GW or fake it.

Of course fake it is the correct answer.

Looking at the decals I decided these two might do the job well enough.

First I applied the House Malinax cog.

Then I painted the center red.

Then finally added the House Makabius 4 pointed star.

Looks close enough to my eyes.
