These were from some of my initial testing with MJ although for other packs, such as the other portrait packs, it has become a smaller part of the workflow but yields far better quality end-results: https://xanthius.itch.io/56-fantasy-avatar-portraits

For the subscription question: Any assets that used MJ in the workflow to any extent were made while having the unlimited tier which grants me the rights to the results.

I find that I'm not as good with rendering scenes so I've been staying away from it until I get more practice, but if you look through my profile you should find a good amount of RPG items which may be useful to you.

For the free items I have two packs out you might want to try:

https://xanthius.itch.io/free-rpg-items

https://xanthius.itch.io/free-fantasy-icon-mini-pack

If you are interested in any of my other packs or items then feel free to contact me and I can put together a custom bundle at a discount for you.

Since you mentioned that you use UE, this is my shop on unreal's marketplace: https://www.unrealengine.com/marketplace/en-US/profile/Xanthius'+Asset+Store

I would suggest buying from itch instead so you get the raw image files instead of uassets. They also dont allow me to list me free stuff there but it has more up to date listings and some packs that havent been uploaded to itch yet.
