SSWAG crit session

Yesterday, January 11th, was the first SSWAG meeting of the new year. SSWAG is Seven Stories Writers and Artists Group. We are a group of writers and artists writing and illustrating children's books. We started at the end of a CLL (Centre for Lifelong Learning) course on writing for children. We are based at Seven Stories which is the Centre for the Children's Book in the Ouseburn Valley, Tyneside.
We alternate Writers and artists at our monthly meetings. This time, my work, Uncle Uriel's Legacy was one of the works being critted. As well as the usual: does it make sense? could you follow the story? would you want to read more? - questions, I had two specific ones:

1. I started out thinking I was writing a book for teenagers/ young adults, but now I'm not sure. Is the writing, especially in the Book of Daniel, too demanding? Should I be aiming at adults?
2. The story is told in two voices: Just Soh's Story - a third person narrative told from the point of view of Soh (Sophrosnia Ecklethwight) - and the Book of Daniel, narrated in the first person by Daniel. I wanted to consider whether these narratives should alternate chronologically: 11/11/18 Soh, 11/11/18 Daniel, 25/11/18 Soh and so on... Or should I tell Soh's complete story, then Daniel's, then the third part where they meet?

The SSWAGgers were extremely complimentary about the writing. I do wonder sometimes whether we are too kind. The consensus seemed to be that the target age wasn't a problem. It could appeal to both adults and literate teenagers. It's not for the spoon-fed, but does that matter?

On the question of how to deliver the two narratives, I'm inclining toward the alternating version, though I will probably write it one story then another. In fact, it's actually the case that I'm writing it higgledy-piggledy. I have written much of the third, joint, part and bits from all over of the other two, but from the planning point of view, I'm going section 1 -10 Soh, section 11 - 20 Daniel, 21- 30 joint. This probably makes no sense to anyone but me. You'll see.
