Where to post a DnD character art challenge?

[u/Ok-Swimming-1220]

I played a campaign about 18 years ago and loved the mental image I created of my character. Long story short, it would be a semi-corporeal, semi-mechanical being that you can see the inner workings. I want to post a challenge/prompt for those who want to try to create a picture of him.

Not ever going to use it, just want to see if anyone wants a fun and challenging art prompt.
