• pearl’s hair, whether intentional or not, is shaped like a rosebud, which is obviously very fitting narratively
  

• sadie gets a gash on her face in “Island Adventure” and the scar stays for the rest of the series as part of her permenant design
  

• Sardonyx has a very cool insect motif; the concept art refers to her as ‘cricket-like’, with six limbs, long legs, glasses that look like compound eyes, and a suit tail that looks like a pair of cricket’s wings, in addition to the much more obvious dragonflies that appear with her
  

• On top of that, her eyes overlap with her hair with the concept apparently being that her eyes are actually on her glasses rather than her face (I’m also really fond of how they basically serve as eyebrows expression wise - same goes for malachite)
  

• Peridot blushes blue underneath her visors. We don’t actually know what color her eyes are
  

some other more basic things i really love:

• Pearl is very lanky and awkward looking in theory (she has a big nose, feet, and hands) but is presented as graceful
  
• Garnet is very bulky and solid looking, apart from her arms, which are as thin as pearl’s. It’s very nice contrast
• Amethyst’s knees (and later, her shirt) being ripped is a very nice touch and goes with what i said earlier about her being a very good example of rare asymmetry in character design
• Steven’s star eyes,, but i mean. who doesn’t love those
• The color schemes they use to shade peridot are very nice (I can’t find a picture but they use blue for shadows and yellow for lights, rather than just different shades of green)
