100% would not remove the sign it's part of what makes the image for me, I do think that it's a really nice image, I would consider making the image a little darker to give it an even moodier feel
But I have to say this is very good especially give the shutter speed without tripod also you've done a reasonable clone job

Cheers mrtoad, I quite like the sign, it has me imagining an ominous little theatre where all sorts may happen. As for the crop you could be right you know, remove some of the total blackness from the top.
