How to paint a Chaos power sword (fast version)

After the build-up of what would be the unveiling of a legendary chaos power sword, results were ... meh. Nonetheless, it does offer a very quick way of painting a power sword. All steps shown below can be completed in about 15 minutes or less. Unfortunately with the sun as the main light source, picture quality was uneven.

1

a) Sword was first undercoated using Chaos Black.
b) Metals parts were then painted the usual Boltgun Metal with a touch of Badab Black wash.
c) Straps on the sword's hilt were basecoated with Scorched Brown, followed by a layer of Bestial Brown, and highlighted using Vermin Brown.
d) A coat of Dark Angels Green was painted on the blade's upper-half in an arrow-shaped manner. Edges of the sword and ridge line down the centre were also painted with Dark Angels Green.

A layer of of Snot Green was added on-top of the Dark Angels Green layer with care, leaving some parts of the latter colour showing,

3

Scorpion Green was then painted on-top of the Snot Green layer. As with step two, when painting be careful to leave some of the darker Snot Green layer showing so as to give an illusion of colour transition from a darker shade to a lighter one.

4

a) Sword's upper-most part was painted with yet another lighter shade of green (1:2 mix of Scorpion Green:Skull White), again leaving some of the darker shade of Scorpion Green showing.
b) Lastly, Skull White was painted on the tip of the sword.

So there you have it. An obsidian power sword in the midst of powering up.
