Can't say this is the sort of thing that really impresses me, but I can say that it is done quite nicely. The picture itself is kind of a neat representation of what you said and I liked it enough to make it my background. But in terms of overall impression this submission was lacking.
I take my art review style like I take different types of women, I mean I'm sure you can agree you know some women who are just plain ugly, some are attractive and some are just plain wow. Well this submission seemed to be just attractive, it didn't have any real substance to it, nothing that made me care for it any more. And that could be for any number of reasons, granted a snowflake isn't all that great of a topic to draw about. But y'know, that was my opinion.
(I could give you advice on brightness and color, but why bother telling you to change your own artwork, you should be able to express your own ability and change it toward your own liking, on your own. Without my technical critique.)
