First of all, you could move the menu up to the top of the screen (more convenient). Better yet, just do a new menu. Maybe split the current images section into a couple image thumbnail pages. On the series information, put an image or two or something from that specific series on the description page. Putting more information about the individual sailor senshi might be nice. Example:
Cumpleaños: Junio 30
Edad: 9 años
Color Preferido: Rojo y Rosa
should be a header for the section, not the WHOLE section, for Chibi-usa.
On another note, you seem to make way too much use of the center tag. I'm not sure which - if any - you would want to change, just an observation.
Pretty good page though, even if I despise Sailor Moon.
