I like the mood of the scene so far. It needs more set dressing, but I'm guessing you're still working on that part. The addition of the Jewish Star of David to your Christmas market is an interesting choice, but cool. (Maybe it's a multi-holiday theme?) There is one thing I think could be improved though. The lighting from the carnival booths is leaking through the roofs, and highlighting the roof tiles in an unnatural way. I also think their volumetric scattering intensity is too high (Too much fog scatter).One last thing, I think the cobble stone with snow and ice could be glossier so you can get some cool reflections form the carnival booths. Just my opinions though. I'm looking forward to seeing how it turns out.
