Bend Loki's back a touch, so he arches looking upwards. And then have Hulk slightly bent forward, and closer. Will give you a more dramatic pose, more intimidating
Cool. They go great together....I guess due to the rag doll scene in A1.
Interested to see what you do with it.
The key to posing [I need to do a "how to" video"] is to get torque in the figure someway. Whether that be a crouch, bending back, bending forward, twisting, or whatever. It implies kinetic energy, like you can feel the next move about to happen. Follow me?
