Commissioned pieces - in process and finished!

Some time ago I did a painting (wood and acrylic) of a dancer surrounded by fire:

 

One of my friends said she loved it and asked if I could turn it into a series for Wind, Water, and Earth.

I can't remember which one I did next, but I have completed all but the Earth one.

Here are is my sketch for the water one:

The finished painting of WATER

 

(figures I can't find a picture of the WIND one)

 

ANYWAY...I started the Earth one FINALLY!

 

(it will eventually be a voluptuous female tree)
