Banshee attack - Book illustration

Greetings hiveans.
I am very Sorry for being so absent these last few months but time is a finite good and I'm trying to get a hold of mine...

Lately I've been mostly occupied with work around our new (old, but newly bought ;) house. But thankfully also I've managed to get some drawing work done. Mainly portraits, but also a few book illustrations.
The one I'm sharing with you today is from a teenage oriented fantasy centered around irish mythology. The scene depicts death of one of the heroes by the hand of Banshee.

Starting with 2b pencil sketch

Then inking with sakura pigma micron 02

adding thicker lines with 05 pen

Finishing large black areas with pentel brush pen
And done.

 
I was wondering how much brutality can I fit in a teenagers fantasy book and finally decided to stick with what you see. What do you think about adding some blood and maybe more gory stuff?
Would you make it more brutal? Or maybe less?
