Queenkami- thanks for pointing out the black pixel, I genuinely didn't notice it at all, thought my screen was dirty as well.
And thanks to the others as well! ♥
Nice one! 
I would have actually left AA out completely, because I think the rest of the piece works well without it. I like how minimal the snow is, too!
I really like everything going on here, the colors, the chunkiness of the snow falling, it's all very good. Your preview image made me think I had something on my screen though, there's a single black pixel on it 
Nice graphic rendering style and very pleasing palette!
