Hi,
Ornatrix works different than Hair&Fur. in Ornatrix you layer effects until you find the desired results. This approach gives you many ways to do the same thing, but you need to understand what every modifier does. So I suggest you to take a look into the documentation.
In this case, the first thing to do is:
Decrease the hair strand width to match your example.
In Hair from Guides, match the hair count from your example using the hair count parameters.
From there, start adding effects. I would start with a Frizz modifier. In my opinion that is all that is needed to match your example.
Add additional complexity using other modifiers.
