Lmao i used to draw the tumblr nose-- Just bc other people were doing it (and bc i wanted more colour in the faces) but now looking back, the sunburnt lobster nose you find in tumblr art makes me laugh-- People try to make art look realistic and then they make a red nose...
Its ok if its just for the art style, but if you want a more "realistic" approach, avoid using a bright red blush on the nose...
