I couldn’t help but give it a try myself :)

Prompt: character design of inspector gadget, wearing a fedora, riddled with biomechanical implants, looking in horror at the viewer, as painted by H. R. Giger
Yes, I know it was a trilby and not a fedora. I only found out after I made this image.

It’s no Giger, but then again I really can’t see how you could blend the two styles without losing what made Giger’s work so unique.
