konichiwa,

i often get extra sketches and douga with orders 
from animaxis, so this is most likely the best 
place for you to post.  while i haven't received 
that particular sketch, maybe someone else here 
has or will in the future.  your best bet is to 
wait and see if it turns up, or to search blue 
gender galleries to see if it's already in 
someone else's possession.  good luck!
