Some people will complain about anything. I enjoyed NTL and I think you did a great job with it. I also liked the graphic novel. You also mentioned The Diamond of Jeru. I finally watched the movie a couple of weekends ago. I enjoyed it. I'd love to see another LL story made into a film though I'm not sure how likely that is to happen now.
Skyring Water sounds interesting. I'll definitely buy it and read it if you ever decide to finish it. Just because you're not your dad it doesn't mean you're just some kid writing fan fiction. You're a good writer in your own right.
