Hello Mike,
Thank you for the "original", and your encouragement!
The time was 4 hrs. for underpainting,and 3-4 for overpainting. I made without any drawing, but immediately started with the underpainting.This was a year ago!After getting some tips from here, I do now charcoal works to establish my drawing-skill. (I'm soo impatient

)

Cheers,
Leslie
