the post is NOT cute. tumblr users actually only sexualize old men as a stress response during periods of acute psychological suffering. if you see your mutual suddenly reblogging posts about 'want[ing] to fuck that old man' and editing cat ears onto members of rock bands or actors from the 70s, or characters from prestige television, it may be time to reach out. in extreme cases, it might be time to consider putting them down.
Anddd I would say that it was by observing all the details of things I like, in movies, music videos, photos, other people's work or in real life.
I focus on one thing that I like and I draw my entire piece around that thing, which can be a person, a color, certain pose, a song, a combination of ideas, clothes, etc. I hope that makes sense.
Also by practicing but my advice is that it is more useful when you observe things rather than just drawing everyday the same things in the same way :p
I'm posting this everywhere and nothing is going to stop me >:)
Anyway I wanted to draw Robin Gibb eating a chocoflan because his hair reminded me of one everytime I saw it haha also I yassified him a little bit because why not.
