I can't say for sure that Union Jack was, but She-Hulk certainly looks familiar! The rest, of course, are by the Forums own Jim Maddox, who indeed credits me for the inspirational poses, or creation of the character.

Very nice collection there.  The Bowen pieces are incredible and nearly always seem to capture the classic look of the Marvel characters.  Of the pieces shown above, I also have She-Hulk, the Sentinel, and the two Iron Man mini-statues.  The other busts in my collection include the Fantastic Four, Captain America, Guardian, Phoenix, Dark Phoenix and Wolverine in his brown uniform.  The other mini-statues include Storm, Nightcrawler, Colossus, Dark Phoenix, Hulk, Thor, and Doctor Doom.  I'm hoping to add the upcoming Puck bust and the Captain America statue.

I also got hooked on the Gentle Giant Star Wars stuff.  I almost need a bigger house to display all of this stuff.

Yup. I used to have my Super Powers figures (now retired) lined up the same way, and people -- people who work in comics! -- would stand there for several minutes trying to figure out the reason for the line-up.
