Massive-Improver

This LoRA should (and will) improve your images. There are some XYZ plots included, so take a look since the picture is worth a thousand words.
Trigger word is not really required but you may use Style-something to enhance the effect (look at prompts)
This LoRA can create mature themes, but it is not deliberately designed to do so, so it will depend on checkpoint used.
Have fun!
