I took the upper jaw and Graphic Gale says it has 697 colors

Either you're that retarded to use a hundred colors on MSPaint or you didn't make this in MSPaint. You also rotated some sprites. Unless I am unaware of a version of MSPaint where you can rotate sprites, then you're lying about using ONLY MSPaint.

You'd know if a sprite were rotated because of the lineart "skipping", or having jumping anti-aliasing. Some parts of the sheet do have both, pointing to rotation.

There are also some colors used in only one pixel over a very large area, particularly the colors you used to aa the edges etc.

Let me guess; you don't even know how to anti-alias properly. You did this in a program other than MSPaint, better confess now, before... Well, my guess is you're pretty much ruined anyway.
