Soot experiment IV final... Working nuances...

I took an hour or so this morning to slap another coat of paint in an attempt to introduce more color nuances...

A few finishing touches in the afternoon gave me more or less what I wanted from this picture. This photo was taken in the bright sun shine...

Note: I used walnut stain instead of soot for the underpainting with this one... but both are very similar in behaviour... I think I will call this one "whirlwind"...
