Is this the old Dark Angels variant?

You should share him over on !oldhanmer@lemmy.world he would fit right in.

Paint job looks good. As you said, probably just the edge highlights could use a touch up. They just look a tad thick. Too much paint on the brush maybe? Also, not sure of your technique, but I use the side of my brush to edge highlight when possible.

That said, the model is not disadvantaged at all by the highlights. Looks better than no highlights!
