About posting OC request image. (Patreon)

Hello,I just need to know about

posting the OC request image (in low-res)

on my twitter or instagram is ok or not.

I am in private account so you cannot retweet it.

If ok, I will add watermark on image and tag your twitter.

And It is free for the owner using only still. You can post on your own sns account.

Please let me know. Thank you!
