your best set yet, imo.
the legs need work, they really dont pop like the arms do.
hands and torso could be less cluttered, the top of the hands look squashed, keep the squashing in mind from the rectangle of the texture, to the square ingame.
i really like the helmet design, but the face doesnt really work. go for something more stylised, rather than cartoony.
and edit the triceps mapping to match the biceps, the biceps are nicely centred, while the triceps map to the corners.
