Small update on the Storm Raven front. I've painted some freehand icons on to the wings. I'm really happy with the outcome of these. They're completely flat, but have a raised look to them. You might also notice I've used a really dark blue to line all the armour plates on the Storm Raven... that took some time in itself.
As to the question about should I weather or not... I'm thinking a little bit of weathering but not too much. I won't chip the armour though, just going to add smoke/exhaust damage to key areas.
