Alchemist Playing Cards - Hands

I've started working on more ornaments for the back and decided to opt for a complete design process taking inspiration from pictures I personally shoot when I found myself at some car boot sale in Wales in September 2018. Moving to digital sketches, vectorialisation and I am still deciding what should these Alchemist's hands look like...

I don't personally mind the clean look with no details but I'll add some more and see what will come out.

Again if anyone could give any feedback that would be absolutely great and help me bring these cards to life!!
