Spider-Man/Black Cat: Evil That Men Do

I've started drawing this artwork at the end of 2018, but then had to postpone it for an unknown amount of time. It looked complicated, in addition, I'm not that experienced at drawing anything but women, so spidey had to wait. Finally, several days ago, I've finally managed to finish the artwork and now I'm sharing it with you.

I've hidden a little Easter egg. Can you find it? Moreover, suggest which comic character would you like to see next.
