I think it looks pretty cool, but the ying-yang symbols need to be moved down a little bit (and you could probably size them up some to fit the space). Also, adding a normal map for the little rock cracks/indentations would help complete the scene.
you don’t know right you are as i had the screenshot as a background picture and ‘traced’ the components so it is an exact scale replica and if you properly read my original post i say i am going to put the ‘dragons’ in the background and use photos of actuall clouds (if possible) in the background
To make cracks in between the stones you need to Normal map them or do them manually. I would choose the last cause that is the easiest and saves much time. Here you have a tutorial on using normal mapping or bump mapping (same thing) http://www-users.cs.umn.edu/~mein/blender/tutorials/dust/bump.html
