This style is trained on the artstyle found in the classic FPS game Strife. It is trained on all the portraits in that game as well as the intermission art screens.
If you want to use it for portraits in ZDoom, note that by default the images are squished to be a bit shorter in the source files and then stretched by the engine. To acheive an effect similiar to strife, I suggest the following steps:
592*424 for Strife; we need 420, but can only generate at 416 or 424
downscale to 296 x 212
crop bottom two pixels so we have a 296 x 210
downscale to 296 x 176 (should look a bit squished)
Overlay the Strife border frame
Use in game! Should unsquish in game
