It would've been more drametic if he had square eyesockets and void for eyes, while having a waterfall of tears pouring from his sockets. I liked the 'dragon skin' texture you gave it. Although it has no sense of luminance. (Although it is also a good thing, not shading too much)
For once, look at his right cortex and the scalp; The shadow on those sides travelles with no regard to dimensions, or at least it looks as if the scalp is lower than the cortex..
Also, by your lil' tale, the creeper explodes uncontrolably and unknownably; which puts to question that stick of TNT.
What I imagined from reading your description, is having a crepper opening his chest-cavity like a cabinet and being upset about the amount of explosives it finds there, with a note "With love, Notch" or anything of that sort.
Overall it's a good image, you shade well & I respect your inability to draw hands :( I hate them aswell.
Verry good.
