Here is my first attempt for a multiple character LORA model.

Here comes brother and older sister Eric and Jill from a well-received early 90s animated adaptation of a classic book The Little Engine That Could. If you have seen it, remember when Eric wanted to see a birthday train full of toys and hopes the train would arrive, despite his sister teasing him and trying to make him lose hope?

For footwear, you may use these tags:

For Eric, gray footwear

For Jill, light gray socks, brown mary jane shoes

If you wish to generate art of both Eric and Jill together, you may want to do some experimenting so you can get the results you want. To start with, you can use the last trigger word in the description.

Enjoy!
