Dear Stephan, Erik, Egbert, Konrad and Carlos thank you for your kind words.
My friend Carlos have excellent holidays.
About Niko's sea:
http://www.modelhania.gr/forum/index.php?topic=474.0Though the text is in Greek the photos explain everything.
In case of my model there is a difference in the transparent waves and sea painting.
The sea is painted with Royal blue, then drybrushed with oils, and finally airbrushed with diluted "pebeo vitrail turquoise 17" which made a thin film.
For the transparent waves instead of watersoluble acrylic (silikon) was used Liquitex heavy gel with continous hits of the tip of the finger. Next day followed by Winsor& Newton medium passed with the finger again, but not hits this time. Finally Liquitex high gloss varnish sealed everything.
