25th & 10th Anniversary Challenge

3. What I need help on in order to finish:
     b. I need opinions about some of the monsters I've replaced, and some of the monsters that were left in a vanilla appearance.  My approach was to leave fantastic creatures alone while scaling mundane creatures down relative to the stick figure humans (which had some amusing results, especially with Ralph).  However, I didn't address any arthropods like the insects or crustaceans.  Should these too be minimized?  I'm also concerned some of my replacements don't work so well, such as Figaro cave which is full of skunks and old ladies.

Well, I can help with giving opinions.
