I decide to give this model some credit but I think it is important for user to know what it is good at and not good at.
I did some experiments that can be found here

According to my experiments, this is a good model to train on if

- You are using orange/anything series and you want to have the styles of the training images

It is not probably the best model to use if
- You indeed want to have style of other models, and especially that of orange when using your lora on those models
- For some reason you want to get style of your training images on something like pastel-mix

Of course you may get different conclusions with different setup, and you can always circumvent the weak point by adjusting various things, but this is the trend that I observe in my experiments.
