@monaloren | Some parts of the UV layout are in x and some in y direction.
If you use the Object Coordinates as input for the noise texture, it doesn’t care about the UV layout…
For the rest, it is beginning to look really good (maybe change scale of the Voronoi on the metal? Something looks a bit off, like silent also mentioned…)
One thing: and maybe this is intentional, but it looks like it is standing on a round table, which makes me think the barrel is really small…
But like I said, that might be your intention, a small table barrel;)
