Well, on top of this one being a grey pegasus with yellow eyes, pigeons are historically associated with mail delivery.Moon Shadow is likewise self-explanatory, from the colors to the wings to the helmet to the very name. The use of lighting, posture & insect imagery in Lucerna gives me Chrysalis vibes, but maybe that's just me. And before any of those I saw Butterfly & Candy Fairy and legitimately assumed they were fantastical interpretations of Fluttershy & Pinkie.There're also various pieces that resemble the other main characters (most strongly Violet Light, Blue Beast, Exousia & Arwoht IMO), but I only noticed those similarities after I'd seen Pigeon, Butterfly etc., made the above assumption and started actively searching for comparisons. In any case, they're all beautiful work regardless of inspiration. I discovered your gallery via your MLP fan-art, but it's always awesome to see so much variety. I'd never even heard of Howrse until I read your descriptions (thanks for that by the way; I explored the tag and found a lot of amazing art, already have a folder of 400MB
