You're welcome Angelus. :)
Also, why don't you post pics now so we can tell you if you messed up? You wouldn't want to make a bunch of Walking frames then have to change them all over again, that's one reason why Blaze took longer to finish, I was amending her sprites constantly. D: It's also not a good idea to do the walking frames first, they're a pain in the neck to do even if you're editing them from another character's sprites, and it's exhausting. The walking frames are the most time-consuming part of almost any WAD, and usually consist of 1/3 or 1/4 of the frames of the total in it as well. D:
Try doing all of the other frames first, like spring up, spinning and gliding...etc. That way all of the easy stuff is already taken care of before you exhaust yourself working on the walking frames, I was glad I did that with Shadow. :)
