@Akito766_Jerboa pointed me to my problem with granulating Mars Black, I don't know who fed it to me about five years ago, but with an ordinary lamp black there is less dirt, noise, better gradient and generally simpler work. An average watcher will not necessarily notice the difference, btw. At the end, there are close-ups of the final work to see closer. I'll post a more detailed comparison later

Some oily stuff also dripped onto my pic between the scan and the thematic photo with teeths outside
Stain was on the photo, but rn you noticed it

So, @desutorakuta asked me to do this charts by his scheme how granulating and non-granulating pigments interact. A lot of noise, and I don't like it. You've probably already seen everything you need here, but if you have any questions, I'll explain.
You can also request a color chart if I have those colors.

(It turns out 511 WN is also granulating 😆 I need to replace a significant amount of the my watercolours...)

Did you get a good look at the teeth in this photo? Here's a closer look 🦷🔍

More photos, but under good light and from more angles

Really not that big. These teeth are probably from a small caudal. They're already quite large by the way.
