In all honesty, a bit of a played topic.

Although, you took a cool approach by sticking your vocab to under water-like. Well appreciated.
You fell off flow a few times, but basically maintained a good one. Solid vocab in here, and structure for the most part was continuous.

Your concept development was alright you had the story evolve and it went on pretty steady.

Props on the drop, only advice would be to space it out a bit, some kids dont' have amazing eyes.

I have 20/20 but I did have to squint a bit.

Props though.
