Don't be afraid of archetypes or tropes. Your favorite character is probably inspired by an older character from a movie inspired by a character from book inspired by folklore inspired by some real historical guy. Don't worry about being unique, be interesting.
@ Every artist who feels burdened by drawing fanart and following trends. This is your sign. MAKE MORE ORIGINAL WORK! Focus on honing your craft!! Make art that you care about and other people WILL care about it!!!!!
