I found a 3D Printed Pug online, stuck on a tuning fork (I made it using my dremel on a large popsickle stick), added a little bit of sculpt around the face (including adding on a toothpick for a tooth) and then gave it a paint. It doesn't have any articulation but will look good enough for me next to Black Bolt and Medusa. I might look at making a Crystal next.

I'm not really looking to become a professional customiser or anything, but I always want to be able to improve, so if you like something about the way I've done a custom, please tell me so I can do that more. And if you think I could have done something better, tell me, and if you've got suggestions on how to improve I'd love to hear them!!
