Hello, after a loooong pause, few months ago i decided to create a doom mod, with the sprites i already realized and a lot of new ones.
Although the mod will of course contain all of them, named, and anchored reasonably accurately... i decided to share sprites, flats, textures here. 

Of course your projects can suggest you many other use for those drawings.
 
The first 2 doors in this collection can be cropped at center to be 64X128 or 64X64 without looking... well, cropped.
They have a "moving object" warning label on the bottom, personally i will use them in a way that leaves the stripes in sight when the doors are raised.

The chef's suggestion so to speak is to imply that use those doors to give the idea that the base where your mod takes place was built over several decades, and so older (or newer) areas have different doors, grids and walls.

I'm releasing a version of each door in true color, that can be converted in any global or local palette (or used as they are, but the quality is not worth the extra weight, those models where mapped and rendered with 8bits palettes in mind.) and a version rendered in DooM's palette.
