Painting the floating hand

Paint

Prime in white, applied by brush.

Basecoat the wood in brown.

Apply streaks of reddish brown for color variation.

Paint the fire. Unlike the relevant painting tip, I decided to start from yellow and go towards red, as a real fire would be hotter at its base and cooler at the tip.

Orange next:

Blood red:

Gore red:

Everything in successive layers, painting less and less of the torch each time, but also doing small streaks down to emulate a 3D flame.
Top it off with yellow glaze for added shine:

For the hands, I wanted to go for the cartoonish white gloved hands.
Basecoat in grey.

Highlight with a thin coat of white. It got a bit streaky...

So I applied a second coat.

Basing

Cover up the base in home made putty.

Then create the rocky base as per the relevant painting tip.

Finished!
