By curiousity, I just checked lux_maya's profile.
It seems that you'll never get your art unless you have another way to contact them as they got suspended on FA.
It also seems that they deleted their boosty, telegram. I'd not be surprised if it's also deleted too.

Ya I just left it up there letting people know it was a scammer.

Oh also did some reverse image searching and the art on there profile is not even their own. It's some Russian artists.

I see.
A true scammer indeed.
Btw, out of subject but you have a really nice OC and gallery
