Well, good news, apparently my grandfather didn't have another stroke, as the doctors are sorta clueless what was wrong with him, but he had several symptoms of a stroke (he has some issues with arteries/veins, one of which is mostly clogged, so his health is always at risk), but he's home now and happy to be home!

As for Hulk, there are so many "versions" of Hulk it's hard to decide what 100% direction to go, so I'm going through a ton more of reference images.

I think my favorite one is the look of this first one, of him facing Wolverine.

What do you think?
etc.
