This looks awesome E, thanks for sharing!
Sue - more powerful pose, more commanding, maybe with one of her hands being a fist. She looks a little too dainty here, like she's afraid she's going to fall. "Toughen her" up a bit. Does that make sense...?
Reed - maybe have him stretching more, so his chest/back is spread wide like flag, and maybe a large fist...?
For enemies , I wouldnt mind seeing a herald like Terrax, or maybe even the Surfer!
Hows that for thinking outside the box?
Keep up the awesome work!
