alright so this is my first critique so bare with me on this!
Firstly, I LOVE the way they touching cheeks! The one eye closed is very cute too ^^ The pattern on the female are lovely as well as the tom. The females isn't very realistic though, but i think that was the point. The eyes, are amazing! They always look so detailed! The tiny little golden heart was very Cute. I like how you made it glow.
The snow is nice, but a moon would have bin great! maybe some stars to show its night. I think the snow on the ground could have bin a bit more detailed, like show some uneven spots and lumps. also where there sitting should have bin indented, as well with the tails.
The snow on the tails, head, and shoulders should have bin thicker. It Kinda looks like fog. The Snowflakes, are amazing! I like how some are bigger and some are very small.
You never fail to amaze me.
