My My arent we a talented little duckie..
LOVELY mate!
It\'d make Frank Herbert proud
as fer the colour, that really depends on the colour of the backing, like picture it in yellow sand ye\'d want a nice contrasting colour, or if it were in red sand (we have that here in Australia, somehitng to do with large amounts of iron oxide in it) youd go for the more yellow orange colour, alternately the skin could be patterned, if nothign else it would help give it an impression of depth and shape (think striped Tshirt, or cow mottling ro tigerstripes)
Lovely model anyways, really nice
