 ### Some recommendations 
 We recommend to set the:
-- prompt as: "<wizard, paladin, healer, etc.>, in the style of 2dart, white background, no background, full body"
-- guidance scale between 9 and 10
-- sampling method as Euler
-- sampling steps as 60
+- prompt as: `"[some wizard, paladin, healer, etc.], in the style of 2dart, white background, no background, full body"`
+- negative prompt as: `"deformed, mutilated limbs, background, multiple people"`
+- guidance scale between `9 and 10`
+- sampling method as `Euler`
+- sampling steps as `60`

+This model was trained using images which the character has some human format or is a not deformed living being. So if you try to predict something like "sword, mirror, candle, etc" (non-living things), we saw the model doesn't perform so well.
