How do I submit my vector chess piece design to lichess?

I've created some chess graphics, with the main goal of having them appear on Lichess.

I like Lichess more than chess.com and I thought Lichess should get its own set of stylish pieces like chess.com.

I got a very positive reception on Reddit, and I've implemented some of the feedback I got on there. I might create more sets in the future for those who prefer a different style.

Very nice!

Maybe custom chess pieces could be a good idea, as we already have custom background.
Very nice design

To be clear, I don't know what Lichess' guidelines are for accepting a new piece set. Presumably there is some feedback among staff as well (for example, they didn't accept my piece set userstyles.org/styles/153638/vvvvvvchess for some reason; also other proposals github.com/ornicar/lila/issues/1701 and github.com/ornicar/lila/issues/3429 are being considered).

''userstyles.org/styles/153638/vvvvvvchess for some reason''

I lol'ed a bit there (:

To comment on #1, I like the design, and I hope it gets featured on lichess

Leipzig piece set (github.com/ornicar/lila/tree/master/public/piece/leipzig) was accepted here lichess.org/forum/lichess-feedback/leipzig-pieces
