A really interesting contrast between the ice and flowers. Good eye for noticing this.
It seems a little soft on the detail, so I looked at the file size. There is some excessive JPEG compression taking away some detail. Your file size is only 65k and you could have used up to 150k for this challenge. Compression kills detail. Always use the least compression you can get away with an still come in under challenge limits. Most image editors have that ability to adjust compression somewhere in the file save dialog. Here is how it works in Paintshop Pro, along with more explanation of compression, if is is of any help:
I also copied this into PaintShop Pro out of curiosity, and found that some easy and basic image adjsutments like levels, curves, saturation, contrast and sharpening really helped this to pop.
Neat idea. I like the effect. I wish there was a little more light on the flowers. I think I would try increasing the saturation of the yellow just a bit.
