Let's Chat: What Makes Fantasy Designs "Good" or Immersive?

This is entirely subjective opinion, there is no "right" or "wrong" (with the exception of poor artistic composition). What are some of your favorite fantasy characters, arms and armor, architecture, landscapes, etc? What is it that you appreciate about them?

It's easy to just rant about "bad" designs, but I figured it would be interesting to discuss the specifics, and consider different perspectives.
