This is very high resolution (10000 x 10000 pixels) collage with 18 real snowflake macro photos, captured at dark grey woolen fabric in natural light from cloudy sky. All snow crystals you see here keeps their original resolution and was not re-scaled, so their difference in size is real.
This collage presents wide range of snowflake sizes and shapes: from simple triangular and hexagonal plate crystals to large and complex stellar dendrites.
I used one of these really nice free canvas textures for background.
