I like this tree and it's always good to see more nana's in use but the trunk bothers me a bit. To me it goes to the back way too far and even though you've pulled the apex back to the front it's still pretty obvious (in a picture at least). Good work though and a long way from a cascade.
BTW , Mr Nagatoshi has procumbus and pro nanas all over the place it his nursery. Some are absolutely spactular ( sp ? ) with thick trunks and lots of dead wood. As far as I could tell all still had the juvinal foilage as well.
