100 heads drawing challenge - 91/100

I challenge myself to draw 100 heads #100headschallenge ( also know as 100 heads drawing challenge )
Usually, you have to do this in 10 days.
I choose to don't follow this constraint because this challenge is also an opportunity to test different medium and techniques. Plus recording take time (/▽＼)
Slowly but surely, I'm continuing this challenge. We're on the 10 lasts heads.
It was a bit messy with my small move; but I manage to keep going ^^ That's why you can see I started to shading with pencil color and end with alcohol markers.
I still don't know if starting with Smurfs' color base to have cool tons was a good idea XD But I'm curious how do you manage this sparkles blue tint with same supplies ?
Here 91/100 head of the 100 heads drawing challenge ♪(^∇^*)
