The hoe (or is a scythe?) will overlap into the next frame as it stands. He's holding it a bizarre angle in any case, should be more to the side if he's carrying it whilst walking.
Shading is alright, though perhaps 1 extra level of red wouldn't go amiss for proper depth. I like the hair, thats fine: nice charcoal effect.
And the eyes aren't very evil...he just looks sleep deprived rather than full of malice. A slightly narrower gaze, perhaps? Though I'll admit that base RTP eyes have trouble with this.
Still, keep at it!
