So.... I then proceeded, extremely carefully, with a borrowed 'dremel' or cheap gypsy version therein, to cut out the bucket's frown and eyes (NOTE: if you're going to do this on a cheap fibreglass bucket, use a set of goggles and mask - i got fibreglass in my eye and it kills, plus breathing in fibreglass is a bit of a no no: http://www.scif.com/safety/losscontrol/Article.asp?ArticleID=373 )

Anyhows, lesson learned.

I roughly cut out the teeth after researching a number of different 'stunt' helmets (www.starwarshelmets.com), and 'dremelled' out the eyes.

This being crappy fibreglass, I then had to painstakingly sand using ripped out small folded sheets of sandpaper the teeth and then work on the eyes for hours on end, until I got the look I was after (Albeit I may have sanded a little bit to much out of the corners of the eyes.... but it still looks good to me)
