Many, many thanks for the overwhelming comments, much appreciated!
The figure is sold as a 54mm but it's size is closer to 60mm. But really wel sculpted and thus a pleasure to paint.
Ed and Maco: the colors I used for this face are the ones described in the tutorial from Jaume Ortiz. Which can be found in the article section.
Einion: Yes, I'm going to add it a bit more beard and will try to smooth the forehead a bit more.
Jim: It's more difficult to paint a bad sculpt well than a good sculpt.
Marc: It would be great to win a gold medal at Euro one day.
Gordy: Don't expect too much, but I will do my utmost best.
Cheers,
Marcel.
