It looks like a religious symbol, with the colour and orientation, and I do not like it as much as the others. I guess it's the orange that I don't take to. But here I am talking personal preference, because, there is no question, all your snowflake shots are well done.
Re you comments on the OM lens, do you mean that you can place an OM lens on Canon camera?

I agree about the orange color. I was rushing to get outside and photograph a fleeting storm, in my haste I grabbed a green and red filter. That is all I had to work with.
A Canon camera can be easily adapted to the following lenses; Nikon, Olympus, Contax Yashica, Leica R. Pentax is little more difficult, Minolta requires surgery. Some medium format optics can be used too.
The mount on a Canon lens is a larger diameter and sits closer to the sensor than most brands. Because of this an adapter can be made to sit between the lens and camera. These alt lenses can't be auto focused and they have to be used via stop down metering and photographing. If this interests you then you should visit this forum,
