Thank you all for your nice comments. To David11 :
As you said, the problem is to do something NOT looking like Krüger's or Mulatier's work on John Wayne. And I can tell that's not easy... Still working on it.
And yes, this is for a special project. A book about "western heroes" with some other caricaturists I'll publish next october.
With Achdé, Jean-Marc Borot, Thierry Coquelet, Charles Da Costa, Thomas Lebeltel and Mulatier himself ! Working hard on that, and I think it will be great... Go and see their websites.
Here are some other sketches... Hope you'll like them :
