This looks so cozy, and the Christmas tree looks nice. Although, straightening out the lines in the background could make this even better. I like the decorations you've chosen for the background, they're very pretty.

This is amazing! You chose a really cool angle for the light, and I like how much detail this has.

Nice clean lines and solid colors. I like the little pattern in the background, it works well with the solid color on the character. Nice work on the pose, but the lighting on the character looks odd. The direction of the light source is unclear.
