I have watched several of these painting tutorials now, and for simply watching... there are some good tips in there. Of course I don't play Tau, but that doesn't mean that there is nothing to be gained from watching it.

Advent Day 8: Daemon Worlds Terrain Guide- Mobile & Tablet Edition:$5.99
DESCRIPTION
Warp storms like the Eye of Terror and the Maelstrom are areas where realspace and the otherworld of the warp collide. When such storms erupt, worlds caught within them are subject to horrifying changes. The surface of such planets is bathed in the stuff of Chaos, and becomes home to daemons and unimaginable horrors, not to mention packs of depraved Chaos Space Marines. And within these storms, such worlds become battlegrounds for the servants of the Dark Gods, their very surfaces shaped by the loyalties of whoever is ascendant in the wars that constantly rage upon them. This eBook provides a guide to painting your Realm of Battle board and Warhammer 40,000 scenery to represent the blasted surface of such a daemon world.
