Holy... wow... sixteen vigs in one post, and all of them are supreme! This brought back some very fond memories of watching the cartoon as a kid, even though I wasn't around for the '60s stuff. Some notes on a few of the vigs:
Doctor Octopus: Great articulation of those octo arms. It looks like a really fast-moving fight.
The Green Goblin: I love the construction of Mary Jane's car. It certainly looks like something she would drive.
Kraven the Hunter: Great use of that construction worker head, and I like his vest, too. It's also good to see Urban Commando again.
The Man-Wolf: The dark blue plates work great as a night sky. It's got a different feel from the black we usually see in MOCs, and more realistic, too.
Madame Web: Love the chair. The SNOT on the dress is also pretty cool.
Mysterio: He and Chameleon are two of my favorite bad guys. Mysterio is done perfectly in this vig.
The Lizard: The ceiling light looks awesome, along with the whole lab. Spidey's picture-taking pose is great!
The Rhino: Destruction everywhere.
The Rhino's footprints are a nice touch, and the use of a revolver as his horn is genius.
The Scorpion: Just the construction of the building makes this a superb bignette. Detail everywhere!
Excellent work, as always!
