The spider in the image above was created by Yorkshire based professional face paint artist Donna. Her 3D spider litertally pops from the skin creating a very realistic and scary life like spider! This technique has proved very popular with face painters across the UK.
The effect is created by painting under the object with a dark grey to apear as a shadow, then using white and lighter tones to add highlights to the top of the object where natural light would be reflected, this creates the illusion the image is no longer flat but raised up from the skin. This technique can be used on all dfferent types of insects and objects.
The below designs are so inspirational and show that anything from lizards to birds can be painted using this effect.

These are true works of art, using the hands to create a 3D face and using characters as inspiration for full facial transformations.
Simply amaizing!
