I happen to have a shot of the reactor core.
I'm thinking the best way to get a close up of some of the things you are asking is to find a random player in game that is willing to go make new toons for you to take pictures of. I assume you can't get what you want from just going into the costume creator then moving your veiw around to see your own costume.
Do you need a generic male hero or civillian? Civillians are easy to find just do a Safe Gaurd with a save the hostage. If you are lookig for generic heros maybe you should do some bank mishes CoV side and see who shows up, those bosses should be a good generic hero type for you. Otherwise, I say go into the character creator and hit the random button.
Thanks Electronite, that was really the only shot I couldn't get myself easily. It was mostly that I didn't think I'd have the time to get them, but I did. If things work out, check out the next City Scoop for the results 
I'm trying to do a little CoX project and I could use some help collecting some screenshots, so if you could help me out a little, that would be great. I'm trying to get these screenshots:
A closeup of monstrous feet.
A closeup of huge bare feet.
A shot of the Terra Volta reactor core.
Two screenshots of a mostly generic male character or NPC.
A closeup of the letter "A" on the chest detail.
A closeup of one of the meaner looking faces.
A good size would be around 150 x 150 or so. All help is appreciated, and I will credit any help I get, thanks!
