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.
That was just creepy.... NOT THE DRAWINGS!!! I mean that it's creepy how saw the Danny and Sam sketches, and so I started freaking out, and was gonna freak out in the comments, but then you said that edit note.
