I'm still very new to this sort of thing, so I'm uncertain how helpful I can be. But these challenges are fun, and I hope to participate myself. Anyway:
1. I like the angle/perspective - it looks very cosy amongst all that snow!
2. The photo looks a little dark, but that could be my laptop.
3. I don't know if cropping or cloning out the snow particles would be a worthwhile improvement - to me, the larger specks look like some sort of u.f.o phenomena!
