It would be nice to have dust/scratches alpha mask for helmets that have plastic/glass/armour shield. It's already great that you guys have masks for welding mask and motorcycle helmets, but I think with additional alpha of some scratches, maybe a bit of dust in the corners it would be even more nicer. It won't change the concept. just will add a tiny improvement that will boost general immersion. If you decide to give it a go I think it won't be time consumable att all, just a good alpha and a bottle of bear for a coder:) Just one alpha for all such headgear would be more that enough.
