Galatea: I never saw the original but I like this remake (the trend was bound to happen at some point). I like the choice of skills you've done as I would have copped out and just done a Enkidu expy, which is actually the reason I've never done a sheet for Pandora either.
Ivan Pavlov: Pretty creative, never considered him as servant material but I like your take on him. Also don't feel guilty about not commenting, you shouldn't feel obliged to.
Harald Wartooth: ... Two EX's?
Wong Fei-Hung: I never saw this guy in materials so I can't comment on that aspect. The sheet itself is fun and I always like seeing martial artist servants here (I say that having only done one myself). The NP is very simple and but it works great with him, also the Fist of the North Star reference was appreciated.
Cain Lily: I should say the new format is a bit hard to read, then again it could just be on my end though. Also considering the sheer length, you may want to start incorporating brackets. The stuff you've actually put down is really enjoyable though with the character and everything and I can't really add on what hasn't been said too much.
