Winter Postcards

The overall composition is great in all the pieces, the only thing I would comment on is diversity of the theme. When one thinks of winter rusty leaves (browns & greens), and snow / snowflakes come to mind (blues / whites). Some elements of snowflakes building a face would have been exquisite. A snowflake or "snow element" encasing one of the faces.

Other than that I feel the colors fit the the theme you were going for very well. I also don't know if any lore or mythology is playing apart of the design decisions you made. Only three of the four pieces give me a winter vibe. The two up top and bottom right proclaim your theme to me. The last one seems a bit more morbid.

Hopefully this feedback was helpful for you.
