On CivitAI.
You're doing a surprisingly good job with character consistency considering that. The CivitAI generator is okay, but it's missing a lot of features you would get with a local setup of A1111 or ComfyUI. The biggest one is ADetailer. It lets you do a second pass for a character's face, hands, or other problematic areas to fix issues. That alone saves a ton of time and annoyance. It really shines with zoomed out and full body shots, where otherwise fine detail would be lost. Upscaling is also nice.
If you have a decent GPU, it's pretty easy to get this stuff set up locally. You can even train (or commission) custom character LoRAs to help with consistency and uniqueness. The current designs and style you have are solid, but I immediately clocked it as the Disney Princess LoRA, lol.
Also with a LoRA for character consistency, you can dial down the CFG scale setting, which means you can have more diversity in images with fewer attempts, while maintaining the character's look.
