David, that looks nothing like my Redgum, but I like it. I got some curly Redgum from a mate in Oz some time back and I love the stuff. I really think I like the look of that pen, but may I make a suggestion? I'd like to be able to see it better... you know, more of the pen, so having the pen itself take up most of the frame would better serve you. Not trying to insult, just making a suggestion.
Something like this, but maybe a tad larger. I really hope you don't mind.

It looks grainy because I expanded the size. By reducing the initial frame size to just larger than the pen, you'll get a much higher quality than my example.
