Nice work! i actually prefer the 3dview shots vs the eevee shots. i see way more details in the 3dview shots. See you had great reference images, how you did get such image?
EDIT
Just read you have “just” 2 years 3d experience with characters and blender. Do you have more years experience with 3d, very impressive results after such short usage.
pS near the end i noticed you using RGB maps to paint the textures. Why didnt you use the “lazzy mouse” feature, that way you strokes are super smooth. Its sometimes called lay-mouse, pull-. I n ribbon. In Blender its now called “Stabilzed Stroke”, you can find it in Advanced under Tool settings, its same as a pull ribbon effect
