Hands not on the sheet:
If "from a photo of my own hand" counts as "from scratch," then yeah. The latter is sized down, aspect-modified, and edited further.
An attempt to fix the lighting and the shape of that one hand.
Mike12 changed the thumb on my reload hand, and I made it less... chubby. I may need to work on the shading though.
A firecan with torch-like flames.
Doom trees (quite tiny, really). Also in Autumn variety.
Gem-powered magical torches.
Automatic Shotgun. Original sprite by WadaHolic, extended 32 pixels by me.
The Freedoom pistol by Scuba Steve, polished up and modified a bit.
Polished up Freedoom plasma rifle.
An old multi-color plasma scatter rifle sprite by me. Plenty more frames, may upload them.
Less angled version of the Glock in Pisstepank's package of weapon sprites. Painstakingly edited with either MSPaint or GraphicsGale, I don't remember. It still needs touching up and is a bit wobbly, but I may fix that in the near-future.
Modified Duke64 pistol. Updated 9/30/13.
Flipped ejection port, reload courtesy of HavoX. Also updated 9/30/13.
Elongated version of the lead pipe that WildWeasel made.
Leever rifle. Credits belong to Scuba Steve, Marty Kirra, Scero, and Snarboo.
Duke3D MP7. Model originally by Teh Snake, then used in Psychophobia; ripped via Blender.
Greatly-edited version of JoeyTD's centered Duke shotgun. Updated 10/10/13.
Interpolated explosion, with/without flare spikes.
Extreme burn death, down to the 4th degree! Flame particles not included.
Putrefied (very rotten) human. Would not recommend shooting or even poking it.
Oh hey, another resource
Doom Alpha mountains with a starry sky.
Asphalt, cracked/not cracked.
Varying shades of COMP. 4th is default shade.
A texture based off of the body of the Skulltag/Zen Dynamics railgun.
A recolored Duke Nukem 3D texture.
