I know that we covered this a while ago, but there is a fine book which shows how to make fine trees like these and other scenic stuff. OSPREY MASTERCLASS TERRAIN MODELLING by Richard Windrow. The book isn't cheap, but it shows some great ways to build trees like Thanan has done. Herb found me a copy from Amazon (I believe) and you may be able to get one from SQUADRON on line. Beware of getting on Squadron's site..they have some wonderful 1:48 and 1:35 kits and materials. Check it out.
