I offer both prints of my pieces and specially commissioned originals in Charcoal and Watercolour.
Basic Watercolour (no background)
Full Watercolour (full colour & background)
Charged by the hour and will depend on complexity. An A3 Piece similar to the Dragon, or Sci-fi ones will cost at least $200-$250, a simpler piece like the wolf would be closer to $100-$150.
