Aww this is so cute! I love the idea so much that the two have a present for each other that is big compared to their body size. And since you took a bear and a mouse, the differences makes it so much fun. Seeing the mouse carrying that huge present for the bear while the bear has this cute tiny one for the mouse. I also like the red tones you used. Red is a difficult color to work with, sometimes it can make something look too aggressive. But you got its warm side here well. Very Christmasy.
