How or what can I improve or change in my crayon texture?

Hi, I’m new to Blender and I’m trying to make a procedural crayon texture. Below is what I managed to achieve. What can I improve or change to make it look better?

Welcome to the forum!

You definitely have a good base for the shader already, from here it’s mostly about adjusting values to make the light reflect in a more realistic way and most of that will depend on two things: the values in the bump nodes and how detailed the voronoi and noise textures are

Here is a modified version of your shader with some values changed (Set it as a spoiler if you want to try some changer on your own instead)
