First of all, off hand.. Fantastic work!
This is really impressive sprite work and the fact that you're working with sprites that are pretty hard to work with anyway, makes it even more impressive. The animations are very smooth and flow well, and just... All of it is pleasing, keep up the great work.
About using the second palette..
That is actually a good idea, however there are things you'll need to be aware of such as; damaging robotnik in the boss rounds causes the black in the palette to flash white and back simultaneously, the fact that the second palette changes depending on the zone, some enemies use that palette (When it's a different colour), and a few other things.
but judging by how well you've sprited the characters so far, you might even be able to look into badnik spriting, god knows that'll be interesting =)
