Terrible focus job.I'm posting this to learn from my mistakes.

I know it's not good.Please pick this apart.The sky is ?? Colors are Unedited and the image is badly out of focus.I used AF :mad2: I Wasn't paying attention.(I was looking at that sky ! } If this image was razor sharp would it have impact ??What would ideal settings be for this type of capture. The sky seems just right. But,how do I expose for the dark areas ?


Settings; F/5.6 shutter 1/160 [/COLOR] wrong ? Camera Custom W/B set at 6500K Circ. polarizer filter in place.The lense is not fast.Sigma 10-20mm 4-5.6 Again,I'm posting this to learn from my mistakes.
