Sorry, I should have been more clear, it has nothing to do with you
It might be far out there, but the basing kit contain leaves, shrubbery, grass etc. Maybe you can glue some of it to the cloaks (for a quick fix) to make them more camoflaged. You might need to get several kits.
On a more advanced note, you could create a net with fine thread, glue and/or green stuff. When the net has almost dried form it on and around the cloaks and fix it with glue. Then take your basing kit and glue as much of it to the net as you wish, I recommend alot. Don´t forget to paint the cloak underneath first! Preferbly in a dark color.
Again, it might be far out there
It´s really cool to have something written here.
