| You can actually see the edge of the decal because it has air behind it. The air is there due to the rough (comparatively) nature of the surface and the inflexibility of the decal to conform to the surface. Anything you put on the top will seal it in but it will probably not get rid of the shiny edge.
A coat of Micro-set MIGHT make it conform better and help but I wouldn't put money on it.
You are probably better putting this one down to experience and doing things slightly differrent next time.
As for varnish, don't think of woodwork varnish. What I am refering to is a clear coat of matt or gloss enamel or acrylic paint. For something as small as this I would use Tamiya acrylic clear as it dries to a very thin coating that doesn't hide detail. All it does is seal in the decal and ensure an even surface finish across the item once you have finished with the decals.
