This one wasn't as frustrating as Kuuga's LoRA (probably because I was looser with the prompts this time), but the oddity here is that because the five Riders have their own aesthetic (well, G4 stole G3's, so four?), they kinda blended together and so you have to be creative in order to bring them out.
Playing with the weights for this one was extremely fun though, since you get to see the forms progressively evolve. I recommend a scaling between 0.7 and 1.
