I've had a box of Hell Dorado demons in my garage since 2007 and finally took them out to paint.
My favourites would be the Greater Demon of Wrath (the big guy) which was a gift from Space Cowboy, the Demons of Sloth (the three sleepy looking dudes) and the Saarlac Pit.
The lava bases were my first attempt at basing other than gravel and flock. They were really easy to do and fun to paint. If anyone's interested:
* The rocks were pieces of cork - you can get packs of four cork tiles from Bunnings for around $14. For most of the bases, I cut the thickness of the cork chips in half using a craft knife to 'lower' the rocks. But for a few I used the full thickness.
* Cut out a groove in the cork chip to fit the miniature tab for metal miniatures
* Glue the rocks onto the base with super glue or PVA / wood glue. PVA / wood glue works well, is much cheaper than super glue but takes longer to dry. Glue some gravel / sand around the edge of the rock but leave some of the base spare for the lava.
* You can either superglue the miniature onto the rock now and undercoat, or paint the bases separately. Either works just as well.
* To paint the bases.
- Black undercoat. I use a black Dulux spray from Bunnings which is half / one-third the price of GW Chaos Black or Army Painter black. Wouldn't try it on miniatures but it's fine for bases / scenery.
- Drybrush the rocks lightly with Codex Grey / mid-grey; then with a very light grey (e.g. Vallejo Sky Grey).
* To paint the lava rocks / stones
- Dark red base coat, e.g. GW Mechrite Red
- Then dry brush with Blood Red, Orange, Yellow and a very light dry brush of White for the very tips of the rocks
* To paint the lava
- Dark red base coat
- A narrower stripe of Blood Red running down the middle
- Then orange, then yellow
- Finally, a coat of Water Effects over the lava (thanks Necroyp for this tip!)
