We all have to start somewhere. altho i have to say, you're starting big.
I would start learning the tool at 1st with just a simple Cube.
learn how edit the mesh. learn how to uwmap it
learn how to apply textures to each face and so forth.
but hey.. this will work too.. just will take some time.
also. i am not sure why you are using a skin node for the eyelashes.
skin is meant for skin.. that be anything from the skin on a football to human skin.
eyelashes is not skin its hair.
For the eyelashes you don't need to do all the fancy stuff you need to do to make skin look good and realistic.
Edit.
I see you are using UDIM ?

I am not sure how UDIM is done in Blender.
Some like using udim, i am not a big fan of it. but to use it properly in C4D The Texture names should be properly named.
Whats nice about using udim is it allows you to use a single material that is using all of textures for misc parts of the body.
But udim may also come and bite you in the ass.
Quick example in C4d using udim for just the color/diffuse channel.
Wait.. gif loading:

Also take a note that the viewport is not showing the textures properly when i use udim in the material. may not be the same in blender.
My point is.. if you are using the udim method. make sure the texture names are done properly.
And the order you index them, you need to look at the uvmap for that.
but daz exports the "index" with the images. the names are just a mess.
