So far so good, buddy. The face is well rendered.
Not sure about the guy in he background, though. And you should probably make the horizon less squint, because it looks like the chimp is on a little big ball, let alone a planet.
nice pose and composition.
One thing that looks wrong, the background character looks stiff,
try putting a stick figure with poses then draw contours or simple shapes,
then ink it.
You made a good inprovement, this drawing is amazing,
nice work, I will see if you can complete and try to help you with it.
If you don't' mind me asking, what program do you use when you draw?
Other than that there's not much to say but well done so far.
