I am not bothered so much about what is in the photo, but the focussing/technical side.
I'm sorry, but I don't know what you mean by this.
For example, consider the issue of focus. There isn't a "right" or "wrong" focus for a photo. You choose what you want to be in focus. Why did you choose f10? Did you think it important for the photo that the building in the background be in focus? I personally think it would have been a stronger image if you had
1) chosen a different background,
2) used a wider aperture (f4 or so) to isolate the horse and leave the background out of focus, and
3) lower the ISO.
On the other hand, if the sky were more interesting and you wanted, for example, cloud texture in sharp focus in the background, then f10 or even higher would be perfectly appropriate.
By the way, it is somewhat easier to remove noise from a RAW file than from a JPG, so the ISO choice can be affected by the file type. The "distances" refer to the nearest and farthest things in the image you want in focus. As for the forum being "mad about post editing", he was just suggesting cropping. The point is to make a compelling image, not to make a "correctly focused" or "correctly saturated" or "technically correct" photo. Those terms barely have meaning independent of the content of the photo.
But if you don't want feedback about the content of the photo or post processing options, perhaps you could be more clear about what sort of feedback you want?
