For the eyes, the shadows underneath the pupils look very out of place. They create a double pupil, and the references I looked up don't have it. I would make them all one pupil instead. The brighter shading above the pupil is lacking. Instead of being a solid color, they should be a gradient going from light to dark, so that it melds with the gradients underneath. For the gradients underneath, you're missing a third color in between the light and dark. Add that color, and make sure to spread them evenly. The gradient highlights on the bottom of the eye are quite extreme. Make sure you spread the colors more so they produce a softer gradient. For the red hair girl, you made the right eye a complete circle, when the 5 other eyes are disconnected. You should leave it disconnected so it doesn't look out of place.
Many areas of coloring do not properly connect to the lineart at the tips, such as the areas on the mouth, eyes, clothing and hair. If you're doing this in Illustrator turn on Smart Guides (Ctrl+U), click the node at the tip of the lineart, and then move it towards the color. The snap effect should work, and the two will properly connect. For the small eyelashes above the eye, and the eyefolds under the eyes, the shapes lack curvature. Make sure the handles at the endpoints are curving either up or down, and not simply straight forward. Also, when you create the bottom eyefolds, make sure to properly connect them using the Smart Guides. If you're doing this in Inkscape, then zoom and and attempt to get it close.
Many of the tips of lineart throughout your image look awkward, especially on the knuckles of the hands. They all look as if you're either placing a node right after the tip, or extending the handles at the tips too greatly, or not enough in some areas. Either remove the nodes, or fix the handles at the tips to correct the areas.
