Its a mix of overdesigning and not working with the setting you're taking inspiration from, it's trying too hard to be "your character" rather than "a character in this world". I should clarify, there's nothing wrong with having your own character be a reflection of you or your likes. But when you talk about trying to fit it in say, Undertale AUs, you gotta be willing to shift your design philosophy to be more about compelling characters rather than your oc who's super cool and important. Even undertale yellow is guilty of this, ceroba is very obviously an oc designed by someone who likes undertale and touhou. Its not a death nail but it is something you'll notice if you don't put the proper mix into it.
