More secondary character ideas. The big guy is a reworked version of the big guy in Concept Work 003. Nothing is written in stone with these drawings. They're good for getting ideas out and seeing old and new designs grouped together. It helps generate ideas for the setting and story of the project this way.
I like the build a bit better on the reworked version and the face on the original. It seems a lot rounder, probably because of the way you shaded there. If you're still going for "protects the weak, but weak himself" for his character type, you might want to play that up a little, because he's looking like a generic-handsome-masculine-protector-figure here. Even as a secondary character, he needs a little more to stand out from the crowd. (TVB is fab, I love seeing all these character concepts )
