As it turns out, that's garish. Eye-bleedingly garish.
So I replaced the red background with a deep blue, and used the red for something I haven't tried before: a snowflake behind the main snowflake, this time using "normal" mode for the brush instead of my usual "screen".
I wasn't sure I liked the way it looked until I experimented with lightening the sky a bit, and tried adding in the teal. It didn't really work as part of the sky, but I was surprised by how well it fit as part of the snowflake.
I still did end up brightening the sky, but subtly, with a faint dappling of lighter blue.
