Certain spots need filling and then of course there is the fact that I simply need Player heads in general:

Spots Available
Jack: Crazy biotic chick. She is awesome albiet nuts. Her spot is going to need a head.
Zaeed - A Merc, also need someone to take his spot.
Mordin - Scientist
Chakwas - Doctor
Other - All other spots around the ship.

The rest of the spots are the crew and they also need to be filled. If you want your head in a specific spot listed above, or just want to give me your head feel free to apply:

I will eventually make a complete list of heads located on the Normandy :D.

 

Clearly I need to be more specific. I need player heads. I'll be editing the original post the reflect this.
