Love it! Box-noughts have there own special charm to them.

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!

Is this the old Dark Angels variant?

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