Shady Shaders: Stylized shader application program (CLOSED)

Hello!
Posting the WIP of my program, written in Rust, that is aimed towards applying different shaders and presets to models. Right now, just loading in .glb models and very basic presets, other features done so far are import and export of presets and screenshotting.  Using the model here as an example with the skin-focused (subsurface scattering, specular highlights) preset. Wondering what y'all think!  

Tweaked the shader settings adding the following:

• Tonemapping
• diffuse lighting / smoothstepping
• exposure
  Also added a special preset for valentines. Smooth gradients, shiny eyes and lips, soft romantic lighting and shadows

I'm now used to the Daz Studio Iray rendering with Genesis 8 or Genesis 9.
I find both images a bit cartoonish, which prevents me from having a truly objective opinion since I'm not very familiar with this universe.
