well that i the hard question

i think leaving that colour as a base would be nice but i think u need to build up some more variations in colour

for example i will use a trex - it has a base of green with grey ontop and black paerts/ spots and brown
which hlps build up the look
here is a quick example of a trex which has this look

i say this but on the same hand i would try to avoid a total pirates of the caribbean remake
