The colors and character design are cute as always, but I feel there's something uncanny about Liena's pose. Her torso is leaning a lot to her right, but her feet aren't positioned to support her shifted center of mass enough. It feels more obvious to me if I imagine the pose without her tail being present. Moving her right foot a bit more to the right would probably help make the pose look more natural while still preserving her line of action from her neck to her left foot.
