Old Death's Head Drawing

It's my birthday but I neglected to produce any special art for the occasion so I had to come up with another idea quick - and this is it: I'm getting old so why not go with an old piece - inspired!

This drawing dates from the late 80's somewhere when I'd have been about half my current age (not sure of the precise date - I just happened to find it whilst tidying up a few days ago). Compare it to my current stuff - hopefully I've improved
