Pencil sketch of Gollum-character drawing/shading study-showing the process step by step

Hi everyone, I want to be here with another pencil drawing from my hands and also a fantasy movie character. This time it will divide and I draw a portrait of a character named gollum from master lord of the rings.
Lord of the rings is a famous movie. Even though I like fantasy movies, I do not really like this movie series. at least not as much as i like harry potter series.
Anyway the face of this character looks like something I want to draw. I drew this same image about two years ago and by comparing these two images you can easily see how much time I have improved from myself.

Final image:

The same portrait that i drew about two years ago:

This drawing took me about 12 hours. may be more(not less for sure).
I used hb,2b,4b,6b and 10b wooden graphite pencil. paper napkin as the blending tool.

I don't know to some people, how do they say that the two years back drawing is the better one. that one i did in about 40 minutes(i don't remember exactly but clearly not more than that).
