New | Practising Scales

Because my hybrid is half sea creature, I wanted to put scales on to my hybrid and I wasn't to sure how to without drawing them on myself, so after looking on the internet I came across a women doing ti with fish net tights, so I tried it for myself at first I used eyeshadow and it did nothing so I tried water colours and it worked well, apart from sometimes it smudged so for my hybrid I think I will only do small patches then there isn't a risk of it all smudging and looking like a complete mess.
Here are the photos of how I tried to create scales.
