The Official M&L3 Ripping Project *WARNING CONTAINS SPOILERS*

[Ridge Troopa]

Looking good so far, but I have a few major nitpicks, one of which you should be sure to fix.
Please leave the shadows with the sprite, don't erase them. This really goes for anyone ripping anything from this game. There is absolutely no sense in taking them out (actually takes more work to do so!), and as I've already expressed when dealing with my own rips, they are completely essential for correctly animating battle sprites.
The second thing is how you arrange your animations. Maybe it's strange that I'm pointing this out, but I just have a really hard time understanding how it's supposed to work based on how you arrange the frames. I think you can find a more straightforward arrangement that doesn't require some sort of explanation as to how to animate them. Visual context is much preferred, as this is artwork we're dealing with.

EDIT: I'm not sure because of how you've placed them on the sheet, but some animations (at least Mario's idle) seem to be missing several frames. I've ripped some of his battle myself and what I have seems to be multiple times longer than some of yours, so just make sure you haven't left out frames anywhere.
