Various entries for various modelling challenges Grant Abbit posted in his Discord server a while ago. After a while, he got too busy and the challenges were moved to another server called Blender Benders
"Retro Game" Asteroids, of course
"Winter" this bastard!
"Lobby". perhaps a hotel, perhaps an office building.
"Pistol" a turret revolver (the chambers radiate from the axis, rather than parallel it)
"Rifle" simple bolt-action
"Rocket Launcher"
"Grenade" pineapple!
"Submachine gun" Sten'nt!
"Turtle"
"Melee" later tweaked and used in my Mara Jade artwork
"Living Room" i think i had actually misinterpreted the prompt for this one...
