These are minifigs of two characters from the video game Tales of Symphonia. I'd like to make custom hair for both of them, but I'm horrible at making such things. I also plan on improving the decals soon, so I may post them when I do.
You pretty much nailed torso details with the decals. As you said, the crazy anime hair needs work, and I think you may need to re-do the minifig heads with grossly oversized eyes (especially on Colette). Maybe some of the exo-force heads would help you. The trickiest parts of Lloyd to build are those gravity-defying tails coming off his collar.
