Demonic P-Bot Love the 3D work; but comments on the story
I know what you've given is a brief summary, but having Tom blatantly suggest that the key is incredibly evil and could transfer to P-Bot is a little sudden and hard to believe. If I were the intern, my first thoughts would be "he's joking". Playing off of that, rather than him "forgetting", having him purposely leave the key in could lead to a stronger climax as he tries to deal with the consequence of not removing the key. If you'd want to make the short film a longer short film, having Tom reluctant to say what the power source is and making the intern find out why he has to remove the key would add a lot to the story.
As far as the design, he definitely looks creepy: with a hint of an ancient feel, as in an old dark feel, which is great when you're talking about evil and artifacts (the key). Is this how PBot will look through out the entire short film, or will he look like his cheerful self in the beginning, and start to look more like this character you're showing us now? Other than that stuff, the image is great. I'd love to see a clip of it in motion sometime. If you ever need someone to play the part of the intern, I'd love to give it a shot; haha
