Looks good! I like the pinks. Try to use thicker lines with the stabilizer on 10 (if you’re using Ibis Paint X). Using different line weights can help, too. As some other people have said, try putting the colors under the outline to avoid the white lines. Some deeper shadows and highlights would be good, too. I recommend learning what layer functions can do because that has helped me a lot (by this I mean normal, add, multiply, soft light, etc). Using a mixture of soft and hard shading can look really nice when doing Episode art. Try adding more details and texture to the hair and eyes. Find an artist you like and observe their art so you can learn from them. I recommend practicing traditional and digital art frequently. You have potential! Keep it up! By the way, I have a thread that has tutorials for drawing noses, eyes, lips, hair, etc. Feel free to check it out if you want!
