The new base has enamel curing on it right now in prep for oils, followed by dust and dirt weathering powders. To get a feel for what it will eventually look like, just imagine the grey areas a dirty steel legion drab color. The important bit for me was to see if the slightly yellow bird head, and the pale green SoH marine would complement Roboute Guilliman or not. When the grey is tan colored, I think the base will sink into the background and give a nice subdued footing to the model.
You might also notice the sword has been trimmed of fire. I do not like sculpted fire, or lighting effects on models, so after a few practice paint jobs, I decided to make this into a more proper looking sword. I plan to use shaded metallics for it, so it won't be glowing.
