Painting Groundskeeper Willie

One of the very interesting characters in the Simpsons sitcom as I've elicited before is 'Grounds-keeper Willie'. I made this particular piece about two months ago for a contest hence the reason why I didn't share it all these while.

I tried a lot to properly interpret the light the best I could do if the placement of the highlight is wrong, please forgive me.
Seeing that this piece is one of a kind, I'm really looking forward to your feedbacks.....

the process...

Its really nice of you to check this out, thanks for stopping by.
