Starlight is an orphan. She lives in an orphanage with other colts and fillies. She has a hard time making friends because they are always getting adopted. She may make one friend only to find that in a month that same friend is leaving with a new family. Eventually, making friends becomes pointless. Starlight finds that those that get their cutiemarks early are adopted quicker, whereas blank flanks are often left behind, because having a cutiemark means having a talent, and having a talent means you are special. This kind of cutiemark/special talent favoritism would 100% cause damage to any growing mind, but Starlight would, of course, take it especially hard because she would not develop a cutiemark until her adult years.
Being forced to watch as the lucky ones got to go to a home, while the few blank flanks, or those that got their cutiemarks when they were older and less cute (and therefore less likely to be adopted) is what could have made her so sympathetic to those who are given the short end of the stick, and so furious at those who stand out among others. Starlight's insecurities and unique ideology would make much more sense stemming from this situation, instead of the canon scenario where she just lost one friend and got jealous and gave up on friends forever like some big dumb baby.
I am a digital artist with an affinity for the so-called "ferals" of anthropomorphic nature (think of the movies Bambi, The Lion King, The Land Before Time, etc), that is, quadrupedal animals that speak and emote as humans do.|
Drawing is simply a hobby for me, though I do occasionally take commissions if I am blessed with free time.
When I'm not doodling or mucking about in the reptile room, I am working at an exotic veterinary clinic, where I wrestle alligators, cuddle prairie dogs, and talk with vasa parrots. My job takes precedence, so my artwork takes time!
