I just went back and watched it. I really like how you used a nice variety of trees to partly obscure the dome from ground level. it gives what would otherwise be a pretty plain glass dome some much needed texture and depth.Some new pics has been added in my first post. Im working on my biodome at the moment. My army of butterflies helps me to get new trees.
btw. what are the dimensions of your main Island? thinking about how much you have fitted inside it I am guessing it must be pretty big.
