modeling that sucker is a pain..did it in Strata and Wings, and still it doesn't look right (especially when you notice the reference pics seem to show an 'evolution', particularly in the tail..;) The reference pics show it as sort of a muted reddish-gold, with lines across it..I have seen a mat like that, mebbe you could try it..
keep 'em coming..

I wish I'd said that.. The Staircase Wit
