The white spot looks almost like a catch-light on an eye. Beautiful capture and excellent tones.

It might almost be an 'earth from the air' shot of a volcanic crater and lake, this. The small area top left upsets the composition, to my eye; I think, anyway, such a regular, graphic image requiress a much more regular composition. Neat, but as an abstract it is too busy for my taste, and as a photograph - well, it could be a created image.

you really stayed close to the challenge, but it left you with an accurate, boring shot.

line "f' (x)=10x+h+9" should have also "h->0" at the end :)
And 10 x 5/4 is not -8
I hope You calculate correctly my points :)
