I'm making a game with a similar style to Hyper Light Drifter, this is my fourth iteration on the protagonist.

Pose:

Run:


I'm looking to get some feedback before I go on with the next iteration/other animations. I was aiming for a sort of grizzled, reluctant hero thing (think Old Snake etc) but ended up in cartoon run territory. How should I go about adding a bit more gravitas to the run cycle and overall a bit more stoicism/weight to the character design without going too far the other direction (i.e. not too gritty and dark)?
