Your art looks very squiggly. It is very hard to see whats going on.
I have a hard time seeing the defining parts of the texture the mouth, the eyes, things like that.
Overall for that second texture, you do not need the snow effect clutter.
It makes for a very messy texture. Try taking some of those effects away and you will find your linework is much better.
The first texture, on the other hand, doesn't look like you put any effort into it.
Looks like you took some random wonky tree background slapped it on your texture, then decided to put some sunglasses on.
If you were to choose one to focus on improving. I would definitely go for the second texture.
