This weapon skin is amazing and I would cover everything I own in it. However: some weapons (like the shotgun and sniper rifle) have a shade of black that's too black.

I would accept this is just a design choice, but other weapons in the pack (Dragon's Fury, Medigun) use a "dark gray" more in line with stock weapons. I feel like if you limited the saturation of black to no more than the default Minigun, this skin would be the best in the game.
