Good emphasis on the eyes and glasses, and I like the hairstyle of the newer image more than the first one.
Re-use the darkest hair color for the glasses in order to free up a color. They are both close enough to black compared to the surrounding pixels to work as a single shade. Strongly increasing the saturation on the mid-blue hair colors will separate the hair from the background.
Maybe try widening the base of nose a bit. I know anime style noses are supposed to be small, but I think a little bigger would be ok. Like, 4 pixels of brown across and then another two on the left, one pixel higher. With a bit of shadow like you already use you can suggest a triangular nose tip, reinforcing the cat face idea.
The base of the mouth is a bit horizontal. This combined with the straight vertical of the nose highlight makes the nose/mouth combo out of alignment with the slight tilt of the head, I think.
The torso has quite a bit of form (boobs and collarbones) but the face is really rather flat. It is inconsistent. The edit below also swaps the hues of the pink and mid-brown (while keeping their approximate lightness) to make the face really pop, but it only emphasizes that the face is flat, so maybe ignore the hue swap.
Honestly, the boobs don't add anything. You could crop it at the collar line and it would look just as good.
