I was always told positive and negative weightings must each add to 1, so for example …(big tits:0.6), (nude:0.4)… and then the tokens without specified weights get weighted on a gentle curve by order. I'm trying to find my old reference and coming up empty, so thought I'd just ask: are you confident you're doing it right, and it isn't just discarding your over-100% weightings? Do you have a link for how your way works and how to choose the numbers?
I'm almost certainly doing it wrong; I only started playing with these tools yesterday. I generate an image, then if it doesnt have the desired result then I reorder words or adjust the weightings or add a negative example to try to guide the result towards what I want
