These are some sprites I made (obviously). In order from top to bottom, it has earth pony, unicorn, pegasus, and alicorn versions, with female versions on the left, and male versions on the right. On the bottom there are recolors for other characters: The Mane 6, Celestia, Luna, and the Background 6 (yes, I know most of the 3-bit recolors are horrible XD ). You can use these for whatever you want, as long as you give credit, and don’t sell anything that uses them without permission from me (and probably Hasbro XD ).
 
Edit: Somehow I forgot to mention that the sprites on the left (top for the recolors) are the 3-bit ones, and the others still use a pretty restricted palette, but not 3-bit.
 
Another edit: Wow, another thing I forgot. Anyway, the “intended use,” for lack of a better description, is, going from the first row to the second and then from left to right: Standing, stopping after running, two walking frames, two running frames, jumping, falling, kicking, using magic, two flying frames, and two “fast” flying frames. Of course, if something just doesn’t make sense (like a flying frame for the earth pony sections), it isn’t there.
