I thought this was a place for idea exchange.

I didn't realise this was a contest.
Well, if you see it that way, that is rather unfortunate.  Sad, really.

There are varying expectations of engineering - "just enough" to get the job done, or robust.

I am sure your circuit works - given the constraints of your particular application.  But the danger is that it may then be assumed to be applicable in the more general sense, for water level indication - a not uncommon question here.

simple board with parallel serpentine etching.

looks nearly identical to the wet leaf sensor

OP is looking at detecting water on the floor in his home not a art gallery.

I does, has been since 2005.

I have 30 yrs experience with electronics and both of the circuits suggested are equally simple and appropriate for a beginner and both should be reliable. If I were in the OP's shows shoes and couldn't use (or obtain) the fluid detector ic I would use either of the circuits. (whichever seems more convenient to fabricate).  My sensor leads for the fluid detector ic were two wires inside of plastic straws taped together  flat on the floor with the bare wires extending 1" from the end of the straws and taped 1/4" apart to a thin piece of stiff plastic (like a piece of credit card cut off of an expired credit card). It worked perfectly . I tested it by dipping the bare ends in a glass of tap water. I really don't see the need to be overly critical of the design for this application.

just to touch on the technology.

a float switch often has to 'lift' about an inch before tripping.

a circuit on the concrete, be it in cardboard, in straws, or a PCB, only needs the presence of water.

lots of good ideas in this thread.  I think the OP cannot go wrong with any of them.

I probably should not be commenting on grammar and spelling as I offer more fodder than most when it comes to offering mistakes for others to find.
