Some very nice Ultramarines Dreadnoughts on display at Warhammer World.
To the right of this pic (cropped as it was blurred, but you can see the shoulder) was the GW Venerable Dreadnought, which compared to the really nice Forgeworld models is horrible. It even looks like extra metal parts added to the standard Dreadnought.
So if you are in the market for a Venerable Dreadnought, spend the extra money and get yourself a really nice resin version from Forgeworld.
