Love the style. That LOOONG neck, awesome dude. I'd say this peice's strength is the animation (absolutely, you did great), and the visual art. And wow, you can paint your backgrounds, too? Good deal, man.
However, I do NOT support the combination of narration + the voice acting, that's a bad unatural mix. At least the way it was done. I even paused your vid to see if the narration would stop or keep talking (to double check if it was in the vid or not) The narration ruined it. If it wasn't there I'd be way more immersed, lol. Not just becuase it didn't mix well, but becuase even the content of what was narrarated didn'td o it for me. I didn't care and I don't even remember what she said.
Not sure if you did that as a 'quick move' to 'wrap up' your cartoon out of being in a pinch for time.
If you did want to do an intentional narration, I would think one of the strongest voices it can come from is the main character. The girl we see on screen. What story, emotions, point of views, or secrets can she share with the audience? Anyway, 3 weeks or less is not a lot of time so yeah, don't worry mate, I got you. I know you can do better and understand that what people produce for their NATA entries may not reflect their true abilities.
Hope this feedback helps you in your future NATA battles. :)
