Guys! I need your help!

1. The sun scene is going pretty smoothly, but I really need your input because I'm not so sure how good of an idea it is, so please please look it over and tell me what you think.
2. The sun now officially needs to be a guy. I understand this makes casting more complicated, but it was going to be more complicated to keep it unisex. 
3. There is a guy in my neighborhood who my siblings think would be a very good Octavian, I'm pretty sure he'd want to do it, but he's a sixth grader. That might not be a huge problem because he could pass as being our age, but seriously people help me here.
