So I want to start designing characters in Friday Night Funkin style. Yet I am struggling to find software on my android phone that can help me.
I don't know how to layer properly, shade correctly, or even how thick the lines should be.

Here's the character I am trying to draw, yet I keep getting stumped and overwhelmed.
Can someone please give me tips and advice, even youtube links would be helpful.
I'm not trying to make a full sprite sheet, just a simple character.
