I finally solved the limpy weapons syndromme ravenants had – I inserted additional magnets at about 90deg to the main one in the torso-arm and arm-weapon joints. I then added 2 more to each joint in the arm bit, allowing it to be attached at 3 different angles at the arm and at the elbow.
Having based the models, I basecoated them with a custom dark grey mix and then proceeded with application of the first layer of highlight so that anything at all can be visible.
And the Ravenants:
I found out I need to mount the running one again at a more upright angle as he’s a bit too wobbly when all the parts are attached.
