Ferry Building

Hi I was wondering if I can get some critique on this photo I took of the SF Ferry Building. It was a windy night, so there is some movement of the flags and trees, which I think is pretty cool. I used a tripod and shot at an upward angle to capture the image. My concern is that the verticals tilt in a bit, look at the left light pole and the right of the Ferry Building. My question is: is this considered aesthetic to have that tilt? Should they be straight? If so, how would I fix that? Would a wide angle lens help?

Thanks

I like it. I don''t know how you are supposed to do it but in CS3 I select the image and then distort it until it's correct by pulling the upper right corner out a bit. That will cause distortion in other areas but they won't be anywhere near as noticeable as this one.

And no, a wide angle will just make it worse. A tilt and shift could correct it...
