Hell of a piece!
Having a 15-foot gator after you is bad enough. If it has usable hands & enough intelligence to make basic tools & weapons, well... My money is not on the girl. She's effectively "treed", like when a raccoon climbs up one & has nowhere to go once the hounds have surrounded it. Also, not too many mostly monochrome pieces on NG like this. It shows how much can be done with hues from a single color (green); the only exceptions are the stream & background sky. Well done.
