Shouldn't be necessary.
Also, I'm updating the first post, you now have one extra week to get your entries in, or spruce your old ones up a bit. Make sure you get them ready by then!
EDIT:
@Insistence, I don't plan for anyone to be working on a head for three weeks straight. But, when you factor in real life obligations with other requests and events an artist can take much longer than three weeks to find time for a Headtexture. Aside from that I know of some heads, like DarkJak's Crysis Head, that took weeks to make.
