Phew... a lot of work... Customer who commissioned this ended up deciding he did want me to go ahead and do the tons of other things we'd discussed early on before I even started that would really make this a Transformers Bladewolf and not just Perfect Effect Leonidas with a new head and a few mods. With all of that done, here's the 2.0 version. Some of the references I went by. The pic the customer said inspired him to get this done.
Dang, it would be terrifying if he did this in the boss fight (but awesome if he did it once Raiden recruited him). Top notch work as always.
