Works well for what it is. Good suspense. I wish you gave us a little something character-wise in that first scene... she seems to be able to hold her own, I got that sense at least, but I want more! Anyways, solid effort.

I'm sure someone caught it already: yolk = yoke.

Criteria met, no issues. Dialog...the last four pages were "Fuck", "Fucker", and "C'mon you snappy little fucker". Not too many points there. I wish I knew a little more about Jen, as such, I didn't really care for her.

That aside, good story though the action was a bit unclear at times.

Good work, writer.

Mayday

from p3 on the read completely slowed down for me. Check it yourself what you might've done wrong there. To me, it felt like the pace of the action somehow is much higher as you actually present it. Imo things should read quick, bang, boom, next, in this whole attack segment…

Okay. It had a heavy action adventure vibe. I liked the p1 exposition the most here. Not a bad story but it didn't have that clear horror feel I must say. Perhaps the chemicals could have burned her skin or the croc gets her, so that she only just got out there in few pieces, alive but close to dead, and I mean really close to dead, if you know what I mean…

I think I give you the criteria since the actual pictures of the snapping croc may be harder than the words in which you presented everything. Yeah, the writing let the atmosphere down here. Anyway, more than solid. Pretty okay. Girl was set up nicely and the general imagery was there.

Pretty good effort here. One nit issue:

Quoted Text EXT. DUSTY RURAL AIRSTRIP - DAY SUPER: Gove Airport, Northern Australia. JEN THOMAS, 30s, tiny frame, angular features and a cigarette permanently stuck in her mouth, kicks a tyre on the chubby Skyfarmer T-400

Is better as:

EXT. DUSTY RURAL AIRSTRIP - DAY

JEN THOMAS, 30s, tiny frame, angular features and a
cigarette permanently stuck in her mouth, kicks a tyre on
the chubby Skyfarmer T-400

SUPER: Gove Airport, Northern Australia.

Reason - a SUPER is superimposed over something. So set the scene first and then do the super

To light the sanitiser and get away alive is a massive stretch.  Also, it's near impossible to see under (I assume salt) water during the night.  There's a few spelling mistakes in there like Jan instead of Jen and yolk instead of yoke.

It was like Jaws but with a croc instead.  Not bad.
