Looking at it again... I love the rocky bottom, but feel that it needs some small random veg in crevasses and definitely some roots from that tree sticking out. Still awesome though. Grass looks great. Jealous that I didn't do this now!
It's no where near finished yet , so what you have suggested has already been started on , but on the other side of the island . I have put a few roots and grass tufts around the back , but I'm not happy with the grass tufts so I'll be altering them in due course . There are shrubs , bushes , trailing ivy , weeds , fallen leaves , decaying wood etc etc all to be planted , but , as you know , these things take time and I want to make sure I plant them in the right order , to save re-doing them later .
Feel free to build your own island . But I somehow I think that you don't have enough spare time at the moment , with all your other projects ,to do it justice . For me , in addition to having somewhere to display my Remora/Lorelei , it is an excercise to keeping up with the latest scenery methods and getting in some practice in rockwork .
I have also been diverted by playing around with my latest purchases which will be used in my next project , which will be even more awesome . Or should that read " aweful" ? That one will be returning to earth and more grounded in reality that this current project .
