Our Comic Lab in the Playground: An experimentation class

[Zexion]

Need a few ideas if anyone could spare them please?

I'm trying to draw an imp character of sorts, which in the universe is question would resemble a mischievous human child. I'm trying to add something that makes it more apparent that it's demonic in origin though. But I don't want to go all out devil horns and tail. Because that's just silly.

Any suggestions? Thanks.

You could give him super-slicked-back hair and maybe very subtle fangs...
