I do see what I would call field curvature or fisheye but what is the big deal ? It is a reasonably good pic.
To me the buildings on each side appear to be leaning inward slightly which would be reduced if you use lens correction, or manual version of that, depends on s/w used.
Of course if using LR or PS then there may be a lens correction file for this cam/lens, google should help. (this is a fixed lens so much easier to flatten than is a zoom which you have to correct for each zoom value)
I have used diff cam/lens correction files (than my actual cam) that helped, canon P&S cams have CHDK which will offer a nearly unaltered RAW/DNG file, and those non jpg files do need both 'flattening' of field as well as cropping (on wide angle settings, you can see the actual barrel of the lens, but you get 4-5mm wider shot !!)
good luck !
