Use clippers rather than blade for tags mate, much safer in the long run.
Looking at your figures, I can't acutally see the benefit of your white highlight over black, its a dry brush not block, it's not zenith (ie reversed shading with thinned paints) and your paints look reasonably solid/good coverage so a little confused. Might be an additional thing that you could actually do without. The scavies could do with a little wash just to bring the shading out, but if it's still wip then all good.

It looks like a technique I picked up a few decades ago, prime black, dry brush white and then you have a bit of ready-done black lining and shading. I haven't used this technique in a while as I've changed scales. I think it looks best with Fantasy figs since I'm not put off by how dramatic the effect can be.
But they look great so far!
What scale are these figs?
