An icon of Saint Nicholas

Hello,
after almost one month without writing anything, the other day I promised to post some interesting things about my wonderful trip to Spain for Christmas time. 

Today I would like to show my new project. I am doing a large icon of Saint Nicholas. 
Saint Nicholas was a historic figure, a Christian bishop who lived in Myra what is now Turkey in the 4th century A.D. 

I brought the old board from Madrid, it's an interesting piece with a shape curved at the top, and the surface for painting it's not flat, it's curved.
My mother gave me a few images of icons of Saint Nicolas, I have to choose one.  
I really like the image in white and black but I must to look for the colours I don’t think it will be difficult.
