I normally first apply Windsor & Newton Matt Varnish by brush. This is more of a satin finish as seen below. I still need to apply a spray matt varnish to the miniature. I use Citadel's Purity Seal (which they actually describe as having a semi-matt or satin finish) to remove the glossy look.
If you think the sword looks too big, take a look at the picture below.
