Thanks, that's a very kind comment! As for secret recipes.. I don't really paint model planes or Warhammer figures and stuff like that myself, but I believe I apply many of the same techniques in my sculpts. Such as paint washing, where very diluted paint seeps into cracks and around details of the figures, really showing the depth and details. Using dark paint for this is really good for a gritty, realistic effect. Perfect for souls-series sculpts. Also I use this kind of shiny varnish for Metal parts like swords and armour.
Most importantly is to not rush such things. Learn to enjoy it. I believe a good paint job can even make a mediocre sculpture look impressive.
