I no you said to work on one sprite but i want to no what you think about the mallow i made

Don't listen to Rakia. The first one is better.
You've put darker shades on the upper right corner of his left hand and the brim of his cap; They shouldn't be there. Also, you'll notice the brim of his cap bends down a pixel as soon as the outline goes outside of his head. If you ask me, it should be straight; if you want to make it curve downwards behind the straight brim, you can, just make sure the outer edge of the brim is straight. I also think you should raise it a pixel higher so we can see his eyes. If you want to slightly curve in both sides of his brim to make it look more rounded, you should be able to do that as well. The lighting on his right foot flattens out on the bottom; make it rounder if you can.

Regarding Mallow:
When you shade yellow, under almost all circumstances you have to hue-shift the color to be more orange (slightly!) so it looks more brown instead of puke-colored (to be blunt) as you darken it. Overall, I think you should practice working with your line art more often because it's line art that really makes or breaks a sprite. Try to practice making more consistent shades; your contrast can be jumpy at times (looking at the difference between Mallow's face and arm as evidence).

'Glad you're working for improvement!
