I don't know how far I'll go with this, I've got a cool idea for a storyline, but putting everything together might be beyond me.
Anyways here's a few shots of four of the five main characters.
First up Malcom, IT support for the office.

Next is Jensen, hotshot of the office and Malcolms nemesis.

Corrine is a copywriter, fresh out of college and new to the city.

And finally Chelle is a hot shot commercial artist on the rise.

I'm working on Julia the office manager/HR lady just now. Hope to have her up in a few days.
There's a few things I'm not sure on. Jensen is looking a bit weasely at the moment. I did come up with a more handsome version, but when I rendered it I came up with a better character idea for it. Chelle's skin tone looks a little cold at present, but I'm going to play with the lighting a bit so that could warm it up. And, given where the story's going in my head, I think Malcolm might need a bit more of a belly on him.
Please let me know what you think of them. If you want to know what props/textures etc I used let me know.
