Yes, you need a larger variety of colors in the shading, because without them, it looks completely flat. MS Paint is fine, but if you're trying to do shading, and you don't want to keep mixing new custom colors all the time, try to find a slightly better graphics editor, (Not saying you have to go with photoshop or Paintshop, but at least something better. I use a 256 color editor for the pixel things that I do, (like my signature) and it turns out halfway decent.) If you can find it, Neopaint is a decent program, though it might be hard to find nowadays. Anyway, the bottom of your pole seems flat too, if it were an actual pole in the ground, it would look a little more rounded.
