First, It's not of any 100 historical accurate!Second, It's v1, might have some minor issue with weapons, costumes, etc.Third, To get this big air balloon use "Airship" only. (Don't use balloon or you will get a balloon)Forth, Try describing color of costume, helmet type, which faction, armor type, etc. (To get best possible results)Fifth, "Knight Armor", is still not the best but close to what was worn.Sixth, Weapons, might not be at it's best, You can type basic rifle, basic hand gun pistol, basic, machine gun, etc. (Or combine any ww1 weapon lora's)Finally, It's a cinematic realistic style, still you can tweak it with whatever model / artistic style you like! Be creative, have fun!
