I mainly focus on side characters or less popular characters who don't already have LoRA. I also tend to make models for older series. I also do my best to maintain the original style of an artist or series when possible, preferring original sources over fanart.
I do take requests, but they'll go onto a list that I approach as I feel like it, so it may take a while for me to get around to. However, if you also provide the buzz necessary for the training (usually between 600-800) then I'll make them a priority.
