I really like the method you used in order to get the spiraling. Some things that you could try in in order to reduce that noise are:
1) While taking the photos, increase lighting if possible. You could try using sunlight, particularly around dusk and dawn (look up golden hour). Trying to light the surrounding area, instead of the subject, will also help because it will make the colors less ‘washed out’. This in turn will make it easier to adjust the colors using the color curves.
2) During post, you could try reducing noise. Particularly, there is a parameter called ‘lens correction’ in darktable that helped me a lot with this.
This photo has a really interesting effect with the two-color tones interchanging in and out of each other. I actually kind of like the grain of the noise in this photo, it reminds me of a comic book or science textbook image.
The full resolution image is so cool! I really enjoy how the brown/golden tones play off of the blue milk. The way you make the vortices was also very neat.
