i think it works well in the first one as its a bit more subtle, it softens the edges and gives quite a dreamy other worldly effect. quite fantasy without being over the top.
the second one is a wee bit much for me. i quite like the house area and it works in the sky but i think to have all the mountains completely obscured doesn’t work. the filter does serve to make the world feel less sterile than it did without though. it seems more like a place that is unstable, in transition or transformation. without it looked static and empty
