this is such a cool one. well done.

Really nice!
I always love the ones done with different media.

Does anyone have any tips on how to post-process or enhance an AI-generated image?

If you’re using Stable Diffusion you can do things like inpainting or img2img to change things - ymmv

Got a mix of dark souls and Viking vibes on this one. Pretty good though. I like this style. I really like to use watercolor when I make AI images. This one would look good in that style too.
