I tend to post everything I get. Sometimes I'm a bit slow to do so.

In the past I have removed pieces though, most notably when I switched to a new account. This had nothing to do with the artists or art quality, but with what the art depicted, and it being something I could no longer show.

I upload everything!!!!!!

I haven't even begun posting things. I had well over a hundred images to upload and more on the way. Please send help. O-O

I've uploaded basically nothing that I've commissioned, but if I did I'd probably post everything, even if it was out of date to my character designs. That said, I wouldn't read too much into it. There's all kinds of reasons somebody might upload some art but not others. There's really no way to be sure so it might not be worth worrying about.

I gave the one I got as a present to my SO :3 They have it now -- I have uploaded it too; But I know we were both thrilled; it was total perfection

The only real criteria is that I made it myself, to be honest. I don't upload things other people have done for me - not because I don't like them, but because I'm a tad paranoid about things like that.

All in all, I'd say there's no need to worry about people not uploading pictures you've made for them.

I uploaded everything, but I'm WAY behind.

Even I try to upload everything but I do it like a sloth from Zootopia

I post everything unless I'm asked not to or unless someone commissions art of my character(s) with theirs without my permission. Fortunately, the latter only happened once. The rest of the time, I'll post it, whether it's a sketchy scribble or the most beautiful image you ever laid eyes on. If someone pours their time and sweat into creating art for me, I treasure it and want to show it off.
