Nice work! The final piece looks very cool, lots of interesting details.
Thanks. I dont think i will cover it entirely in varnsh, but the stones do look a bit to shiny. Or is this needed to cover everything in varnish in your opinion?
So people usually put varnish on minis to protect the paint job, especially for pieces that will receive a lot of handling during games. In these cases, a satin or gloss varnish works best, since they are harder than a matte varnish.
But for display pieces, there is no real need for protection. Sometimes a varnish can be used to "tie together" parts of a piece, where the different inks/paints used may have different finishes (shininess).
Coating these different colors with a varnish will give them the same finish, and unify them.
And varnish can give an interesting effect by itself too: I usually coat eyes, lenses and gems with clear gloss varnish, this makes them look extra shiny and (in the case of eyeballs) wet,
whereas a matte varnish can really enhance a bone color.
Having one part of a model shiny, while other parts are matt is a way to add contrast to your models.
