Ooooh! Great stuff! Fantastic infact!
You're very good with texture. I'm quite impressed. The only thing I don't like is that you make your characters noses white. I know it's supposed to be shine, but it's too much. They can do without it completely.
And as for the two trees, I like the one on the right best. It has a unique style.
Also, I think it's cute that you made yourself as one of the characters. hehe
