Outward Bound

OK...I'm a geek. Any advice which gives my writing more depth and warmth would be appreciated. Also, if I made a grammar error...don't hold back!

I am experimenting on telling the story from different points of view. Not sure how effective that is but I try to give it away early in the chapters about who is telling the story at that point. Mostly, it is from the perspective of the main character, Justin. But other times, Mira and Kate and others chime in for a chapter. It's kind of fun to write however, also easy to mess up, so please look for inconsistencies for me to fix! Thank you!
