Hi Monika - just a few comments from me. I think the scene is potentially interesting, but really needs more of a human element to lift it up a level, perhaps a couple in the nearest table would help.
Also, the sky is overexposed with no apparent detail - I'd go as far as suggesting a landscape crop starting from the bottom and finishing maybe about a third of the way up the image...that would get rid of the troublesome sky and give a nice compact feel. I'm not overly keen on the colours, but there is almost a Parisien feel here that may be helped by the crop.
Finally - the signature - it's distracting and pointless, even if someone wanted to steal the image the sig could be cropped or cloned out. Sorry.
