hello~, here are some of my suggestions.
Please take a look to check if they aren't different from what you meant.
> I took on the spirit of Yamato Nadeshiko's elegant female ghost.
>> I showed elegant Yamato Nadeshiko's spirit of actress.
* I just wondered where 女優 (=actress) has gone.
> Before this, we also did a scene in a lo~ng corridor filled with mirrors.
>> In front of this, we had set up a lo~ng corridor filled with mirrors.
> Ruined...
>> Tumbled donw... (or Fell down...)
> These moments of anger after the ruin leave me broken, but I still smiled--
>> Though it was me (that tumbled down), I couldn't help laughing because I tumbled down so spectacularly.
* I didn't get serious impression like ruined or anger. This part reminded me of that ayu slipped down at Saitama arena some years ago
> BISH. (Hoho, I've decided...)
>> BISHI. (Hoho, I've done perfectly...)
> This scene was then dubbed over
>> I'm dubbing this scene (with comical lines) as I please
(after "Please view the next photo...")
>> ready? then, let's go.
OK, thanks again for your good jobs as always~~
