I love the soft style you have here. It doesn't feel too harsh, or too dull. The characters are unique in their own ways too, yet still somehow manage to be simple.
It's difficult to render two people interacting sometimes, and you've gotten it down almost perfectly. The only thing I could really complain about in that field is maybe the female's leg being a bit too raised. I feel like it would've been a little better if you made her knee touch the ground.
You also may want to consider cropping out most of that white space, unless you plan to build upon this later and throw in a background.
Other than that, this is really well done. Keep up the good work. c:
