Excellent
Very pleasing, but I'd suggest (to the viewers) watching it more than once to get the full story.
I didn't catch that his parents and humans were likely killed while defending the planet from some dark terror and he was shoved into that protective plant so he'd survive on my 1st watch.

I look forward to the rest.
