That's an older wallpaper from me and I hated to draw the mountains, 'cause that was my first time, that I ever draw something like that x_X
But it was a lot of fun to add the snow on Sayuri. First I also added some on her nose.. but well, I deleted it, but here cute puppet got snow on it's nose XD I also liked making the foot prints of Sayuri and a bunny. I also wanted to make bear foot prints, but I sticked to the bunny ones.
For the lake I used a stock image, I was too lazy draw my own X_x
Ah and look at the font, I added some snow to it too XD
