Skin

1. Base in Blue Horror
2. Add gradient with Kakophoni Purple for extremities & spikes
3. Wing limbs in Blue Horror , membrane in Purple , Kakophoni Purple and blended with Blue Horror

Here is a tutorial similar to what I did for the wings: https://youtu.be/IlNsoNgCY9A?si=ow0FfPE9Bvl0_U4m
I went for a slightly transparent/stretched out effect by building up to the lightest shade in the center of each membrane, then highlighting with the midtone.

Armor

1. Trim in Retributor Armour
2. Plates in Blue Green
3. Magenta blended out with Kakophoni Purple to the mutated bits on the wrist & shoulderpad)
