Thank you guys very much, it is always great to hear nice words that cheers me a lot.
Tony Dawe: yes Tony it is probably my very best figure so far, but I have still a lot of energy to paint and I really enjoy it.
My receipt for the black colour in oils:
This part a consulted a litle bit with maestro itself Ernesto Reyes and he suggested me to prepare a mix of medium red, indigo, burnt umber and black a highlight it with the colour of the flesh. It really worked well, but then I found my own way,that was a little byt easier. I did a mix of Van Dycke brown with black and highlighted it with Naples Yellow some corrections with pure van dycke´s brown and pure highlights with naples yellow and it also worked well.
hope I gave you some good tips about this problematic colour.
best regards to all,
Robert
