Hello,

I tried your scene and this is the result that I get:

This is the expected result, considering that:

1. There are not enough guides/curves to cover the whole scalp
2. You are not using a distribution/multiuplier map hair Hair from Guides to determine the hair growing area
3. You didn't setup the parting plane/map/groups.

In case you need to know more about hair interpolaiton we explain it here: https://ephere.com/plugins/maxon/c4d/ornatrix/docs/1/Basic_Concepts.html

1. and 2. What's happening in your scene is that Ornatrix doesn't have enough information to interpolation the hair as you expect. Hair from Guides will generate hair in the whole scalp because you didn't stablish any area limit using a texture map, so areas of the scalp that do not have guides will get hairs that are just an exproximation of the guides in other areas. With this method the groom will not look as you want because you don't have enough guides, so you will not get enough control over the shape of the groom. To solve this, either add a texture map to limit the growing area to only near the guides that you have there. Or add more guides. 

3. In the guides you have a parting on the front, but the interpolation doesn't know about this parting because you are not telling it about it. Correct parting settings will tell Ornatrix how the hairs should be interpolated to each side of the parting. To create parting you can use the parting tool found in Hair from Guides.  You can also paint a texture map to represent the parting, where each side of the part is a different color. I would go for the parting plane tool in Hair from Guides.

I can see that there is an issue with the transforms when grounding the generated guides. We are looking into this and I will keep you posted.
