Note that the game is family-friendly, so please don't post anything sensitive in its spaces.
Wasted buzz by not adding more pictures, but it does generate Flan properly, although sometimes mixed with Astral Charm — unless you find better color descriptions or something that understands "gamboge", or just add "blue hair" and "blue eyes" to negatives. See below for a wiki description that might work. too.
The hair can also become green instead, and something other than hair can become striped.
Not sure if shadows and anatomy are sometimes bad due to the LoRA's deficiencies or not.

I haven't tried it, but https://legendsofequestria.fandom.com/wiki/Flan has the following description in addition to the more technical one with the gamboges:
Flan's in-game character has a beige coat, with a darker beige and light brown/orange highlighted mane and tail, and light orange/yellow eyes. Her Talent Mark is a flan. Her dialogue picture depicts her as having a long, flowing mane and tail, as well as wearing a white, frilled apron.
Here is what she looks like in the game. The smoother NPC version:

the low-poly 3D version:

Here is the reason elements of Astral Charm appear (it just happened to be one of the few images tagged as well as the others in a directory I had tried to train on. It is also a good one.):
