I'm relatively new to fursuiting, but I have some opinions... Cookie cutter costumes are boring! During Halloween, most kids want to be whatever is popular on TV or in movies. This means that you see 25 kids wearing the same Storm Trooper or Iron Man costume that their moms bought at Wal-mart. Your fursuit reflects your personality more than you might think. Unique markings are a very good idea. I suggest doodling/sketching your ideas out on paper until you figure out what you like best.
