I think that looks great! The barbatos looks really good with panel lining in my opinion, especially on the head!
The only thing I don't like is the black lining on white, I feel it's too strong
I know, that's why I used alcohol and tried to make it fade and look greyish
Does pencil work?
Haven't tried it yet, bet its hard to remove cause of where the lines are
Mechanical I mean
What do you think?
