I think this is a really good shot
The building blends so well into the scene, and the colours complement each other too.
Difficult to say if a more angled view would have been better or not, (as we can't see the view from the sides) but I think it would be worth doing just to see. You can always give them two or more pictures!
In the event that you only took this one shot - slap your wrist! With this subject I think I would have taken several shots from every angle I could get, plus some close-ups of the many interesting elements of the store.
