Love your beanpole Lu Ten. I tend to have him fill out and get stocky like his father. Maybe Iroh was a beanpole when he was a kid? OK, probably not, but still. Boys in that family do seem to take after their grandfathers more often than their fathers. Ozai and Zuko bucked the trend, but I wouldn't be surprised if Lu Ten did not. You can see quite a bit of Azulon in him.
