Your first sausages looked really weird, with the contour curves not matching the shape's flow and being so eccentric and not changing sizes, making them all look flat. You've mostly fixed these problems by Organic Intersections, but you're still cluttering the drawing with many unnecessary contour lines: you should dial them down a little, you don't need two of them back to back if the flow doesn't really change dramatically.

Some of your Form Intersetions look weird, they are quite hard to follow: to fix it you could add some lineweight on the edges closer to the viewer and around the intersection.

Your textures look good, but on Intersections you should make the shadows more dynamic - heavier on the edge, softer on the inside - to not clutter the drawing.

All in all, besides these things I think you got it, in Organic Intersections you got volume down pretty well, so I think you're ready to move on.
