If you're a "artist" artist (2d drawings, paintings, etc.) post pictures and you can add a description and stuff.
If you're a music artist post a link to your music video/mp3 or youtube video
If you're a sculpture/ceramics/3d works artist, post a picture.
If you're a dancer, post a video link.
If you're a writer, write some of your poems/prose down. If you can't because it's too long, post a link.
Good day to you all!
(ps. I made this discussion for people who want to post their stuffs on this website but don't feel like going through the whole Deviantart process)
