I’m working on the Luchador masks lots of folks have requested over the years and I’m struggling a bit because I don’t know that world at all. Here’s what I have so far, what direction should I go from here?

Should I be adding seams to make them more realistic? Come up with a set of x patterns (the yellow area shapes) that get repeated across different eye/nose/mouth shapes? Make a blank overall head/mask pattern, then add individual eye/nose/mouth shapes that you could apply the skin color to, then mask eyes/noses/mouths to from their sets? Add shading for that interior head color on all items (the yellow area on that first example)? Ears or no ears?! I’m floundering!
I really don’t know where to go from here. I also haven’t found a great image reference for these so I don’t know what kinds of designs are useful.
Help?
