There's another Lora of the same character that's way better than this one, since it's creator actually knows what's they're doing, this one's ok for my first attempt, also the grey eyes can sometimes have weird colors, lowering the cfg scale to 5 will fix that(but not always), also using the anime screencap prompt gives a much accurate look otherwise...well just look at the first images i made below

1boy, solo, anime screencap, male focus, kiel, grey eyes, short hair, blonde hair, x hair ornament, green capelet, light green shirt, long sleeves, belts, brown pants, green footwear, green gloves
