That's a valid point.
My daughter was showing me some HSL shading that looked better than what I've been doing but I haven't taken the plunge yet. She does some color theory stuff that I don't understand but it looks really good. If my stuff is a 5, hers is at least an 8.
I'll just say that I'm aware and know that it's an area where I can improve 
It's unlikely I'll get into that soon though. I'd probably need my kid to patiently show me that stuff a few times for me to understand it in a useable way. That would require me to pull her away from her other interests. I hope to get there some day.
Maybe I just need to bribe her with guitars lol
