I Need a Few Pointers

[Mother Kojiro]

I've mostly finished my sprite sheets for Willow (NES) - I just need to put in my annotations - but since this is going to be my first upload, I'd just like someone to look at this and tell me if it's okay.  One concern I have is that some of the sheets are on the smaller side, and I'd like to know if my signature is a bit too big and overblown.  Another is whether I should put all of the monsters on one sheet or give each their own; it will be enormous in the former scenario, but there will be very small ones in the latter.  Note that the Slime sheet has not yet been annotated.  Any criticism is welcome; I know that I'm a newb!  Thanks!
