nasty black lines

i spent about 45 minutes rigging all the “rays” of this cartoony sun to get them to “wiggle.” it’s the first time i used armatures for a big project.
when i render, i get these ugly black lines. :confused: :spin: :no:

the sun is made of curves. could that be the problem? please help this is due soon and is my first big project! thanks.

edit dont worry about that wide area in the top right thats flat; thats supposed to be like that.

Try with SELECT ALL in EDIT mode and ALT+F few time.

Also solved my problem ( http://blenderartists.org/forum/showthread.php?t=168161 ) --> thx
