JoeButler's Sprites

[Chris2Balls [:B]]

I suggest you work on a darker background, preferably a desaturated colour: this way you can create contrast more easily. Your eye will calibrate the colours accordingly, as seen in your sprites on white backgrounds (low contrast but high value colours because of white).
The duck's bill looks unusually low and thin. I thought it was a yellow kiwi at first, that's how misleading it is.
Anyway, looking forward to more original sprites!
