I know I can't be the only trying to generate sexy/scary vampire ladies and been disappointed by the results.
Tags
'Bloody hands', 'blood on clothes' and 'blood on breasts' are self explanatory.
'Blood on face' should look more like they got sprayed with blood or injured, 'bloody mouth' should look more like they've been drinking blood.
'Blood spattered' should indiscriminately spray them in blood.
You'll want to use parentheses most of the time.
Observations
'Blood spattered' and 'blood on clothes' are inconsistent, sometimes barely putting any on them, sometimes covering them properly.
Seems more effected by style LoRAs than I anticipated, if you're having issues I'd lower the weights on your styles or increase the weight on the LoRA itself before doing anything else.
Increasing the weight on the individual tags increases the spread of blood, to a certain degree. Most noticeable on 'bloody mouth'.
Adding 'blood' on it's own seems to help prevent it from interpreting what should be blood as paint or fabric when on other parts of the body (only really noticed this when using 'blood spattered', but it might effect the other ones too).
Will continue testing and update if there's more.
