He's quite an entertaining character, but that sprite needs a lot more work.
You don't HAVE to be a good artist on paper to make decent pixel art, but you should really practice a bit more.
For starters, the line art really needs to be cleaned up. Those jaggies need to be smoothed and the overall anatomy needs to be fixed.

Next is the shading. Right now he's really flat and his shirt comes off as oddly polygonal. Light wraps around objects; not layer through them.
And the colors need some work too. Do more than make a color lighter or darker. Hue-shift around to some different shades. If your working with blue, you can go to purple or green(purple is better in most cases) and change saturation around too. It all depends really. Just try things out.
Checking the spriting dictionary will help tremendously
