Taken across the street from Lambeau Field in Green Bay, Wisconsin, USA. Wasn't really that dark outside, I guess it was something to do with the autofocus for why it turned out so dark, but I kinda liked the effect anyway.
I think this is a shot with a lot of potential. It does appear underexposed. This wouldn't have been autofocus but autoexposure. It probably gave too much weight to the sky (which is brighter than neutral gray) and underexposed. You kind of have to get a feel for when your camera is going to do this so you can compensate or bracket, or if your camera has it use a spot or partial meter and figure the exposure yourself.
ANY WAY...the composition is good and the sky was certainly interesting. I think this would have had more impact shot on a contrasty slide film like Velvia. Properly exposed, the flag still would have gone black (emphasizing shape) because of how contrasty Velvia is, yet the sky would have come out very rich and saturated (emphasizing color).
This came out pretty good as is, and I think you did a good job.
