In the words of Elvis: Thank you very much!
Not to worry - the tops will be dealt with - I've left them open at the moment, because I'm a bit undecided about making the canopies.
Also, the trunks needs highlights and vines/lichen/moss etc. so all will be dealt with!
One of our Gaming Group Guys suggested some more heavy logs that was broken in 2-3 pieces and maybe 1 or 2 with a open cut to expose the inner core - Dagnabbit! - Now I want to do just that!!
Another suggestion was a large "area terrain" with only tree stumps and painted to look burned off - I'm never getting out of this Jungle am I?!?
