I get some folks like the whole practically-completely-blank-page-except-for-the-ID-and-some-links aesthetic. But that's uh, that ain't my thing? :y I think a mix between a streamlined-ish page and a handful of stamps + custom css looks really nice.
and yeah on the flip-side.. users with neon pink kawaii uwu backgrounds and 50+ stamps/gifs and youtube embeds and commission info splattered all of the page with no rhyme or reason is like instant back button imo
yeah for some reason the almost empty pages makes me think the user either abandoned the account or something bad happened that's why i've never done that and i can't even load those pages filled with gifs @_@
Depends on the artwork or what you'll be featuring. Do not spam your page with widgets and tons of stamps, a few should be just fine :3 Also, try to keep looking professional as much as possible if you tend to sell.
