Late on that but the very first colour/design on the second line looks pretty good to me.
The only one that really don't match for me is the middle one again on the second line (even if I like the blue...), and his design looks like a merchant...not sure if that's what you're searching for ?
But looking at your composition progress I guess you're going with a warrior ^^
I know this is maybe just me but...try to make him more "alive", with a run or a special attack, no ?
Otherwise, playing with the shapes is a good feeling
I know that's maybe sounds weird but try to be your character, what's he doing, what he feels, etc...gives emotions to your piece !
Hope I'm not going too far haha
