Walter,

I am an absolute newbee in Bonsai so don't pay to much attention to this, but I think the big jin on top is too large. If I look at the tree my attention is drawn to the jin instead of the trunk and foliage. So in my (very) humble opinion it should be shortened a bit. I think the rest of the tree is fantastic. I hope to make something similar in 15 years or so :-)

rgds, René
