Nice, then go hybrid: keep the cool reflections as your base, glaze in warm ligths near windows, and if the mix runs short, punch one bold sky strip to anchor it. That combo defnitely sells depth without needing exact paint. Maybe start with a coo'l water wash, then tap in tiny amber dots so it feels like Venice at dusk :) What do you think?

I don't think that I will be coloring Venice again anytime soon. I have bought other sets that I want to color first.
