Nothing wrong with the picture. Personally, though, I was seriously distracted by the shape's non-snowflake nature. (snowflakes are 6-sided). Did that thought distract anyone else???
Simple, indeed, I like the snowflake-shape a much. :-) Could be in the left bottom corner so the skater and it would give the diagonal to the photo. I guess you wanted to go for rules of thirds, but sometimes it's good to break the rules. :-) I would see the skater more sharper, too, maybe a quicker shutter would have helped you. I like that his movement has a direction to the bottom left corner, this is why I would have composed the snowflake there. Just an opinion.
