Hi,
is there a way to implement these 'lines' to my chracter in CC3? I've tried, but couldn't find how to do it. If it's not possible, will advanced morph pack allow me to do it?
Thanks!   

You might need the essentials pack (if the following sliders are not in the base content) then you could crank up the 'Crease Inner Cheek' and tweak the 'Cheek Depth Inner Right & Left' ought to get close.

It's actually more of a mapping issue than a modeling issue.  A good map should handle those just fine:

This here is really all just maps:

Thanks, but what is a "map" and how do I do it? Sorry for the noob questions, I own this software for like a week..

If you select the face material for any character you will see, in the diffuse channel, a "map" which is just an image that conforms to the "mapping" of the face.  It gives color and texture to the face.  Additionally, there may or may not be "bump" or normal maps, which contribute to the texture by fooling the eye into thinking the surface is raised or lowered.  

Good maps are what separate a cartoony head from a realistic one (not that there's anything wrong with a cartoon head -- just a different style).  Artists can create them, you can use photographs to cut and paste, or you can get them from other resources (the image I showed you is a Daz character brought into CC3 via Transformer, complete with the maps the developer made.  Those maps can be saved and then applied to other characters with different facial features to create a brand new character).

I have cut face from the original image and used it as a bumb map. Some bumbs showed up, but there were not in the right place and I don't need all of them - just these 'lines.' Is this even right way I'm doing this? What should I do? Although thanks, I really do appracitate your patience..

EDIT: I found a tutorial on how to do this. Thanks a lot for your help, have a nice day!
