Ok Malti, real talk. The black lines are driving me nuts. It's cool that you're using different colors for lineart. The blue lines, they nice, they cool. But you have to commit to the blue lines. You can't just make most of the lines blue, then decide that all the lines on specifically the face are black. The lil ocd monkey goblin in my mind is screeching rn. Either make all the lines blue or find better lineart techniques.
Sorry for sounding mean, just being truthful. The zombie is cool and Michael J Fox is funni. If you need any tips or advice on using the art program you're using, just message me. I'm happy to help.
