everybody!
I making a Barbie style doll model. I've UV mapped the face part and created her eyes and lips using photoshop and saved the texture as a png. The face has a node setup for plastic looking skin and I would like to add my texture over it.
I've found similar questions on this website but the ones I found were for older blender versions and I couldn't figure it out how to do it on Blender 2.91.
Below is my current node setup and also the texture I want to apply.
