Please resize the images and please attach them to the post. Wouldn't hurt if they were easier to read too, try to take pictures under a lamp.

You should have no negative charges on the carbons, first of all, nor should there be a positive charge on O. Second, I always count the double bonds as well as the lone pairs.There should be at least 4 resonance structures, because there are 4 double bonds. As it is, I can only see 4 resonance structures. Keep moving them around from your first resonance structure (where O is a single bond and has a negative charge).

(edited because I gave the answer)
