This movie house lobby has great potential as a lovely subject, It is clearly a difficult one as the poor lighting causes the camera to be set such that you cannot avoid producing digital noise.
There are too many anachronisms in the image to make it convincing for the year you've chosen--the strand of Christmas lights and the numerous, small, computer-printed color posters just give it away.
I like the idea here. The grain, the old looking colors are fitting of an aged photo but since this is 1928 I think you would have been better served making this black and white.
There's either camera noise, or too much post processing. The image also seems a bit out of focus. I would have liked to have seen this in a sepia or B&W.
